Didya Know

Did You Know graphic[Another HV twiticism©™®: discrete daily data deliveries in 140K-char chucks; whereas most tweets are rapid & vapid, our twiticisms are slow and substantive. The first was from Bucky Fuller. Next up…]

“Did You Know (Shift Happens)”:

The top 10 in-demand jobs in 2010 didn’t exist in 2004.
We are currently preparing students for jobs that don’t yet exist…
Using technologies that haven’t been invented

Provocative statistic, no. Or more accurately: Provocative statistic? No.

More like a mythstistic. The info above is from the popular “Did you Know?” video. It turns out, tho, the “fact” was wrong when first uttered in 2004, and remains wrong today. The “top 10 in-demand jobs” today all existed in 2004 — half existed in 1904 (nurses, teachers). See the excellent essay “Fact or Fiction? Maintaining Credibility.”

Like many Internet Age “stats,” we want to believe, it matches our worldview, so it must be true. We let perception trump reality, and perpetuate concepts seen on YouTube, heard in some conference, or read on some blog. No research, no fact-checking, just repetition.

With email, txtng, IM, FB, tweets, etc., we are likely reading and writing more lately (not less, as some believe). We’re all becoming de facto published journalists. Perhaps over time we will develop some journalistic instincts, like tracing info to its independently verifiable source, not gulping down data from far downstream — where it’s become tainted and polluted.

“I think we’re in the midst of a literacy revolution the likes of which we haven’t seen since Greek civilization.” –Professor Andrea Lunsford (Stanford Study of Writing), quoted in WiredThe New Literacy

Many millions of us have enjoyed the “Did You Know” videos (at bottom of page). HV especially liked its lineage: a humble start as a high-school slideshow, later animated, xplaned, 2.0ed, 3.0ed, funny 4.0ed, f’real 4.0ed, and parodied by Barely Political:
Video from Barely Political

The original video is fact-packed. HV figured some may want to access the info w/o having to watch the whole movie. We began this project simply to put the text of the several video versions on a single webpage, accompanied by sources and updates.

In following those sources, tho, we were led less toward “Did You Know?” than “How Do You Know?” — what makes us think we know what we think we know? So, on this page and on our twit feed, HV presents…

2. The 25% of the population in China with the highest IQ’s exceeds in number the total population of North America.

Re-statement of pop data above. Would be true for any 25%-of-China-pop subset; 25% w/ largest noses, etc.

By 2012, the smartest 25% of children in India will be
200 times smarter than the fattest 10% of children in America.
By 2015, the former will be eaten by the latter.”

3. China will soon become the number one English speaking country. [wrong]

Wikipedia: List of Countries by English-speaking Population
By Total English  (Native and Second Language) Speakers:
1	United States	251,388,301
2	India		90,000,000
3	Nigeria		79,000,000
4	United Kingdom	59,600,000
5	Philippines	48,800,000
…18	China		10,000,000

These numbers are hard to pin down. See the talk page for this article, which includes this China-related explanation:

Wikipedia’s India estimate of 350 million includes two categories — “English Speakers” and “English Users”. The distinction between the Speakers and Users is that Users only know how to read English words while Speakers know how to read English, understand spoken English as well as form their own sentences to converse in English. The distinction becomes clear when you consider the China numbers. China has over 200~350 million users that can read English words but, as anyone can see on the streets of China, only handful of million who are English speakers.

4. If you took every single job in the U.S. today and shipped it to China, China would still have a labor surplus. [no longer true]

Was true in 2007, but likely no longer: See Research Institute of Economy, Trade and Industry China Shifts from Labor Surplus to Labor Shortage” September 11 2007. Also, Asia Times China’s cheap labor pool running dry June 19 2007 (cites study by China’s Development Research Center of the State Council).

6. The average young U.S. baby-boom worker held 10.8 jobs between the ages of 18 and 42. (Two-thirds of these jobs were held from ages 18 to 27.) [updated]

US Dept of Labor: Bureau of Labor Statistics:
National Longitudinal Surveys ("Number of Jobs Held in a Lifetime')
Average number of jobs for persons ages 18 to 42
in 1978-2006, by Ages:
Total	18-22	23-27	28-32	33-37	38-42
10.8	4.4	3.3	2.6	2.2	1.9

The above DOL: BLS: NLS reports: “The average person born in the later years of the baby boom held 10.8 jobs from age 18 to age 42.” Not surprising since: “nearly two-thirds of these jobs were held from ages 18 to 27.”

And contrary to common Internet Age expectations, this average number of jobs seems not to have shifted much the past two decades:

DOL: BLS "Median years of tenure with current employer for employed
wage and salary workers by age and sex, selected years, 1996-2008"
1996      1998      2000      2002      2004      2006      2008

Also see DOL: “Employee Tenure Summary.”

7. Length of time with the same employer- Ages 18 to 22: 72% of their jobs ended in less than a year; 94 percent ended in fewer than 5 years. Ages 38 to 42, 31 percent ended in less than a year and 65 percent ended in fewer than 5 years.

US Dept of Labor: Bureau of Labor Statistics:
National Longitudinal Surveys: "Number of Jobs Held in a Lifetime"
Cumulative percent distribution of duration of completed employment relationships
Ages	<1year	<2yrs	<5yrs	<10yrs 	<15yrs
18-22	72.3	85.2	94.1	97.1	98.0
23-27	59.2	75.9	88.8	94.0	95.7
28-32	52.5	69.7	85.5	91.6	93.6	6.2
33-37	42.8	60.7	80.6	88.2	88.9	11.1
38-42	30.5	46.6	65.1

Although job duration tends to be longer the older a worker is when starting the job, these baby boomers continued to have large numbers of short-duration jobs even as they approached middle age. Among jobs started by workers when they were ages 38 to 42, 31 percent ended in less than a year, and 65 percent ended in fewer than 5 years.

[“DYK?” vid quotes Ian Jukes in “From Gutenberg to Gates to Google (and beyond); Education for the Online World” (pdf). Jukes asserts the erroneous: “The US Department of Labor now estimates that today’s learners can expect to have 10 to 14 career – not 10 to 14 jobs, but careers.”

That’d be news to the DOL:

The Bureau of Labor Statistics (BLS) never has attempted to estimate the number of times people change careers in the course of their working lives. The reason we have not produced such estimates is that no consensus has emerged on what constitutes a career change.
—US Dept of Labor: BLS: FAQ

How many times does the average worker change careers? Statistically speaking, no one knows. One idea that is commonly — but incorrectly — attributed to the U.S. Department of Labor is that people change careers about seven times in a lifetime. But the Labor Department does not gather that kind of data.

8. According to former Secretary of Education Richard Riley, the top 10 in-demand jobs in 2010 didn’t exist in 2004. [wrong]

Seems 4 of the 5 in-demand jobs not only existed in 2004, they were also around in 1904:

US Dept of Labor & Dept of Educaton: "Top 50 In-Demand Occupations"
					Need for
					Employees	Projected	2006 Media
Top In-Demand Occupations		(2006 - 2016)	Growth		Hourly Wage
1 Registered Nurses			1,001,000	18-26%		$29
2 General and Operations Managers	  441,000	  0-8%		$43
3 Physicians and Surgeons		  204,000	 9-17%		>70
4 Elementary School Teachers		  545,000 	 9-17%		Annual: $47K
5 Accountants and Auditors		  450,000	18-26%		$27
6 Computer Software Engineers	  	  300,000	  27+%		$40
7 Lawyers				  228,000	 9-17%		>70
8 Sales Representatives	  		  476,000	  0-8%		$24
9 Computer Systems Analysts	  	  280,000	  0-8%		$35
10 Management Analysts		  	  264,000	18-26%		$34

The source of this oft-repeated miscalculation is a 2004 book, now out-of-print, The Jobs Revolution: Changing How America Works. It quotes fmr Edu Sec Riley: “None of the top 10 jobs that will exist in 2010 exist today, and these jobs will employ technology that hasn’t been invented to solve problems we haven’t yet imagined.”

Turns out Riley guessed wrong in 2004. So why do we continue to perpetuate the mistake in 2009?

Read how one guy took on the task of tracking down some facts: “Fact or Fiction? Maintaining Credibility,” Retail Industry Leaders- Newsletter 2009-04-06:

So, I went in search for the original comments from former Secretary of Education Richard Riley. It turns out that he did say this and was quoted in a book titled: The Jobs Revolution: Changing How America Works. But, here is the important fact that solves the mystery — the book was published in 2004. If you go back and look at the quote, it now seems clear what has happened.

In 2004, Riley was making a prediction that he likely intended to make a point about how the pace of change would continue in the upcoming years. That is far different than reporting his prediction as a fact in 2009 when it has clearly not come true.

9. We are currently preparing students for jobs that don’t yet exist, using technologies that haven’t been invented, to solve problems we don’t even know are problems yet. [NOT]

Same source as #8 above: fmr Edu Sec Riley. Same result: his 2004 guess about 2010 has been proved wrong in 2009.

10. Name this country: Richest in the World, Largest Military, Center of world business and finance, Strongest education system, World center of innovation and invention, Currency the world standard of value, Highest standard of living. The country is: England… In 1900. [maybe]

Lotsa variables here. We found sources for few. But this project has become an exercise is fact-checking, so maybe some of our readers wanna join in the obsessive misery… I mean, source-finding fun. Here’s as far as we got:

First of all, England is a country on an island — Great Britain — which is part of the United Kingdom. So when DYK? sez England, let’s assume they mean the UK.

The UK’s military, the British Armed Forces was likely the strongest in 1900. But the “largest military” may have been China’s. The Qing Dynasty threw 600K at the First Sino-Japanese War, 1894-5. The closest I could find for the Brits was 250K in the 1853-6 Crimean War.

All this info is from Wikipedia, btw, so second-hard at best. We’ve gone google-eyed trying to find better figures, and are now giving up: maybe someone else will have more success — the best search term we tried was “troop strength.”

FYI, the British Empire was the largest ever, at its 1920 peak reigning over 25% of the world’s population and 25% of the Earth’s landmass — just squeaking by the Mongols, and a good 10M km2 larger than the various Russia/USSR monoliths.

As to what country was “Richest in the World” in 1900: the metric is GDP, or GDI, once called GNP, soon to be PPP, for which the IMF and CIA have differing data, but neither had nada for 1900. ‘Course for “Highest standard of living” take all above and add “per capita.” Couldn’t come up w/ bupkis on that either. Case closed on this one.

12. In 2003 Nintendo invested 140M $USD in research and development. [true] The U.S. Federal Government spent less than half as much on Research and Innovation in Education. [false; US Dept of Edu 2003 budget- Research: $229M]

I wish we’d spent some of that money teaching “Research” to those who repeat DYK? stats. Nintendo indeed has a budget line-item for R&D, but the US Dept of Edu has none for “Research and Innovation.” Thru 2007, tho, there was:

Budget of the United States Government: Fiscal Year 2007
Department of Education (pdf): Spending
2007 Estimate- Research and Statistics….. $554M USD

Nintendo Annual Report: Consolidated Statements of Income (pdf)
2007 Actual- Research and development expenses….. $370M USD

In 2003 those research-dollars totaled $140M for Nintendo and $229M by US.Dept.Edu. Starting 2008, the US dropped an Edu line-item for Research and Statistics. The word “research” does appear in the description of a new program:

“The American Competitiveness Initiative includes an array of research and education programs that focus on improving the Nation’s long-term economic competitiveness.”

Estimated 2007 spending on ACI programs: $412M.

13. One out of every eight couples married in the U.S. last year met online. [doubtful]

This figure is based on a 2004-4 Harris Interactive online survey of 5,000 married couples, sponsored by eHarmony online dating service. A subsequent 2006-7 online survey of 10,000 couples found the numbers even higher:

Nineteen per cent of the couples met online compared with 17 per cent who met at work and 17 per cent who met through friends.… In the current survey, 31 per cent of married couples aged 45 to 54 met online, against 18 per cent of 20 to 44-year-olds.
New ScientistGo online to find your future spouse” August 2008.

Trouble is, no info is given on whether this survey was a scientific polling of a random sample or a “self-selected opinion poll” — known as SLOP in survey circles, for good reason: with SLOP the sample isn’t random, so the results aren’t representative of the general population.

Because the sponsor is a company with a stake in the results, the survey is worthy of heightened scrutiny. Neither the newsroom of eH or HI mentions the survey.

I’m no Nate Silver, but I do know that without info on methodology, margin of sampling error, or even a list of the survey questions, it’s impossible to gauge the statistical value of the results — if any.

And, let’s face it, asking an online-only audience about whether they met online kinda skews the results. What about the nearly 20% of US that aren’t online? Far as I can see, they aren’t even considered. One more thing: how many married folk do you know that met online? Is your figure anywhere close to the survey’s “31% of married couples aged 45-54 met online”?

When you see the words “online survey” chances are that it isn’t a probability-based sample, although it could be. You will want to find out more about how the respondents were selected, particularly if the survey claims to be representative of all adults in the U.S.

Alcatel-LucentBell Labs announces new optical transmission record and breaks 100 Petabit per second kilometer barrier: Equivalent to sending 400 DVDs per second over transoceanic cable.”

Paris, September 28, 2009 – Alcatel-Lucent (Euronext Paris and NYSE:ALU) today announced that scientists in Bell Labs, the company’s research arm, have set a new optical transmission record of more than 100 Petabits per second.kilometer (equivalent to 100 million Gigabits per second.kilometer). This transmission experiment involved sending the equivalent of 400 DVDs per second over 7,000 kilometers, roughly the distance between Paris and Chicago. This is the highest capacity ever achieved over a transoceanic distance and represents an increase that exceeds that of today’s most advanced commercial undersea cables by a factor of ten. To achieve these record-breaking results the Bell Labs researchers made innovative use of new detection techniques and harnessed a diverse array of technologies in modulation, transmission, and signal processing.

23. 300 million new personal computers shipped worldwide in 2008.

Reuters iSuppli lowers growth for global 2009 PC shipments 2009-05:

The latest forecast meant that global shipments of PCs, which include desktops, laptops and low-cost netbooks, will likely hit 301.5 million units this year, up from 299.4 million units in 2008, based on iSuppli figures. –

Notebooks to outsell desktops in ’09, says iSuppli

Global PC shipments are expected to decline to 287.3 million units in 2009, down 4 percent from 2008, the first year-to-year contraction for PC shipments since the Dot Com bubble burst, according to a revised forecast by iSuppli.…

ISuppli predicts that shipments of desktop PCs will decline to 124.4 million in 2009, down 18 percent from 151.9 million units in 2008. Entry-level servers — which iSuppli includes in its definition of PCs — also will suffer a decline, with shipments falling to 6.9 million units, down 9.5 percent from 7.7 million in 2008, the firm said.

Notebook PC shipments in 2009 will rise by 11.7 percent to reach 155.97 million units, up from 139.6 million in 2008, iSuppli said.

24. The $100 laptop project was expected to ship 50-100 million laptops per year to children in underdeveloped countries. [not yet]

OLPC’s “$100 laptop” is now the $200 XO.

“At least 750,000 kids — a number that will double by June, Chairman Nicholas Negroponte said — are tapping away on One Laptop per Child-produced XO laptop keyboards.” —CNN Laptops bring lessons, maybe even peace” 2009-03:

“Only about a million OLPCs have shipped so far.” —UN DispatchOne Laptop Per Child – The Dream is Over” 2009-09.

25. By 2023 the computation capability of a supercomputer will exceed that of the Human Brain. [maybe]

petaFLOPS 1015
teraFLOPS 1012
gigaFLOPS 109
megaFLOPS 106

Neither quantifying the brain’s computational powers nor predicting a future supercomputers specs is easy, or possibly accomplishable.

The original DYK? prediction mistakenly used the year 2013. But their source, Ray Kurzweil’s 2001 “The Law of Accelerating Returns” (full excerpt below), sez: “We achieve one Human Brain capability (2 * 10^16 cps) for $1,000 around the year 2023.”

Kurzweil defines his “cps” as “calculations per second,” and conflates it with FLOPS, one of two common computional metrics:

FLOPS = FLoating point Operations Per Second.
MIPS = Millions of Instructions Per Second.

Kurzweil’s 2001 essay also forecast “IBM’s ‘BlueGene’ supercomputer, now being built and scheduled to be completed by 2005, is projected to provide 1 million billion calculations per second” (i.e., 1 petaFLOPS).

BlueGene never hit petaflops-itude. But its IBM successor, Roadrunner, did in 2008:

The new No. 1 system, built by IBM for the U.S. Department of Energy’s Los Alamos National Laboratory and called “Roadrunner,” achieved performance of 1.026 petaflop/s—becoming the first supercomputer ever to reach this milestone. At the same time, Roadrunner is also one of the most energy efficient systems on the TOP500.

Now here’s Kurzweil’s 2001 cortical calculations and suputer projections:

Here’s My estimate of brain capacity is 100 billion neurons times an average 1,000 connections per neuron (with the calculations taking place primarily in the connections) times 200 calculations per second. Although these estimates are conservatively high, one can find higher and lower estimates. However, even much higher (or lower) estimates by orders of magnitude only shift the prediction by a relatively small number of years.

Some prominent dates from this analysis include the following:

  • We achieve one Human Brain capability (2 * 10^16 cps) for $1,000 around the year 2023.
  • We achieve one Human Brain capability (2 * 10^16 cps) for one cent around the year 2037.
  • We achieve one Human Race capability (2 * 10^26 cps) for $1,000 around the year 2049.
  • We achieve one Human Race capability (2 * 10^26 cps) for one cent around the year 2059.

Others have expressed gray matter in MIPS:

It takes robot vision programs about 100 computer instructions to derive single edge or motion detections from comparable video images. 100 million instructions are needed to do a million detections, and 1,000 MIPS to repeat them ten times per second to match the retina.

The 1,500 cubic centimeter human brain is about 100,000 times as large as the retina, suggesting that matching overall human behavior will take about 100 million MIPS of computer power.
—Hans Moravec “When will computer hardware match the human brain? 1997

The above Moravec likely ended up in this oft-repeated mis-quote:

A human brain’s probable processing power is around 100 teraflops, roughly 100 trillion calculations per second, according to Hans Morvec, principal research scientist at the Robotics Institute.
—Michelle Delio This Is Your Computer on Brains Wired 2002-11-19

She seems to have transposed his “100 million MIPS” to her “100 teraflops”? MIPS and FLOPS measure different things so don’t convert.

But the mis-quote stuck — there’s 100s of Google hits for the exact phrase: “A human brain’s probable processing power is around 100 teraflops.”

She also repeatedly misspelled “Moravec” as “Morvec” and Wired posted this warning atop above article:

Reader’s advisory: Wired News has been unable to confirm some sources for a number of stories written by this author.

Once again this page’s info-quest becomes a hunt for how information originates, morphs, and moves. So, moving on…

Notice the suputer specs above are in FLOPS, so we’ll need a FLOPS estimate of cerebral power for comparison. (MIPS are now known as Meaningless Indicator of Processor Speed, aka, not the preferred metric.) Oxford University’s Future of Humanity Institute put out a Brain Emulation Roadmap (Nick Bostrom and Anders Sandberg 2008) with “Estimates of the computational capacity/demands of the human brain” (Appendix A, page 84 pdf | scribd). Some figures are in FLOPS. Of them, Kurzweil’s above 2*1016 FLOPS (20 petaFLOPS) is by far the lowest. Others range from 1018 to 1028 FLOPS.

So when computers will catch up? Dunno. But IBM Roadrunner’s recent record is a mere 1015 FLOPS, i.e., many orders of magnitude to go.

26. By 2049 a $1,000 computer will exceed the computational capabilities of the human species. [who knows?]

Ray Kurzweil took some guesses in his 2001 “The Law of Accelerating Returns:”

Already, IBM’s “Blue Gene” supercomputer, now being built and scheduled to be completed by 2005, is projected to provide 1 million billion calculations per second (i.e., one billion megaflops). This is already one twentieth of the capacity of the human brain, which I estimate at a conservatively high 20 million billion calculations per second (100 billion neurons times 1,000 connections per neuron times 200 calculations per second per connection). In line with my earlier predictions, supercomputers will achieve one human brain capacity by 2010, and personal computers will do so by around 2020. By 2030, it will take a village of human brains (around a thousand) to match $1000 of computing. By 2050, $1000 of computing will equal the processing power of all human brains on Earth.

Of course, this only includes those brains still using carbon-based neurons. While human neurons are wondrous creations in a way, we wouldn’t (and don’t) design computing circuits the same way. Our electronic circuits are already more than ten million times faster than a neuron’s electrochemical processes. Most of the complexity of a human neuron is devoted to maintaining its life support functions, not its information processing capabilities. Ultimately, we will need to port our mental processes to a more suitable computational substrate. Then our minds won’t have to stay so small, being constrained as they are today to a mere hundred trillion neural connections each operating at a ponderous 200 digitally controlled analog calculations per second.

But as pointed out in #25 above, his back-of-napkin brain power estimates were several orders of magnitude lower than any other.

Well, loyal readers: That’s it for our DYK? updates, sources and errata. Here’s some miscellanea…

For help getting started on the last couple source-checks, much thanks to Doctor Recommended for “FLOPS, MIPS, Watts and the Human Brain.”

Keep in mind, tho, some like neither MIPS nor FLOPS as computational metrics: “Of all the misleading performance metrics out there, MIPS and GFLOPS ratings have got to be two of the most widespread.” —Ars TechnicaBehind the benchmarks” 1999.

In Feb 2002 Smart Computing attempted to aggregate computer/brain comparisons in “The Great Race: CPU Speeds Close In On The Human Brain” (pdf).

The 2003 Oracle- Think Quest project’s Computer vs The Brain had this version of Moravec’s 100 MMIPS estimate in “Man Vs Machine:”

Overall, the retina seems to process about ten one-million-point images per second.

Because the 1,500 cubic centimeter human brain is about 100,000 times as large as the retina, by simple calculation, we can estimate the processing power of a average brain to be about 100 million MIPS (Million computer Instructions Per Second ). In case you’re wondering how much speed that is, let us give you an idea.

1999’s fastest PC processor chip on the market was a 700 MHz pentium that did 4200 MIPS. By simple calculation, we can see that we would need at least 24,000 of these processors in a system to match up to the total speed of the brain !! (Which means the brain is like a 168,0000 MHz Pentium computer). But even so, other factors like memory and the complexity of the system needed to handle so many processors will not be a simple task. Because of these factors, the figures we so childishly calculated will most probably be a very serious underestimate.

The current Blue Brain Project is “the first comprehensive attempt to reverse-engineer the mammalian brain, in order to understand brain function and dysfunction through detailed simulations” (Ecole Polytechnique Federale de Lausanne in Lausanne, Switzerland; Henry Markram, project Director). Here’s one of their FAQ:

Is the brain like a computer?

In some ways yes, but in most ways it is not at all like a computer. The brain performs many analog operations which cannot be performed by computers and in many cases it achieves hybrid digital-analog computing. The most important feature of the brain that makes it different from computers is that it is constantly changing. If the resistors and capacitors in a computer started changing, then it would immediately malfunction, whereas in the brain such equivalent properties change constantly on the time scales of milliseconds to years. The brain is more like a dynamically morphing computer. We are still far from understanding the rules that govern the brain’s genetically and environmentally driven self-organization in response to external stimulus.

As for state-of-art silicon, this from Wikipedia IBM Roadrunner:

The US$133-million Roadrunner is designed for a peak performance of 1.7 petaflops, achieving 1.026 on May 25, 2008… Roadrunner occupies approximately 560 square metres (6,000 sq ft) and became operational in 2008. The DOE plans to use the computer for simulating how nuclear materials age in order to predict whether the USA’s aging arsenal of nuclear weapons are safe and reliable. Other uses for the Roadrunner include the sciences, financial, automotive and aerospace industries.

The trouble with these statistics – despite being wrong! is that they risk dating really quickly. Even the ones about 2008 sound out-of-date because it’s 2010 already! I love predictions like the one about a computer surpassing the human brain by 2023 – didn’t people in the 50s expect us all to be living on the moon by now? ;)

I often provide updates on what’s new and different with technology in our building and what teachers need to know to get the year started. But this year I’m really focused on staff development and the “vision” of where we should be headed, so I wanted to do something different. I don’t know for sure how it is in your schools, but I imagine they are like mine- a faculty meeting is a horrible place to have the conversations we need to have. In addition, since 49 of my teachers are involved in the staff development described elsewhere on this blog, I felt it would be a waste of time – and possibly counterproductive – to try to discuss anything of substance in the faculty meeting.

We began this project simply to put the text of the several video versions on a single webpage, accompanied by sources and updates.Nice information, many thanks to the author. It is incomprehensible to me now, but in general, the usefulness and significance is overwhelming. Thanks again and good luck..
