Gates, Musk e Hawking estão errados

Para o autor do texto, as máquinas não vão eliminar tantos trabalhos como várias pessoas imaginam.

Quincy Larson quotes Bill Gates, Elon Musk and Stephen Hawking as he warns

There’s a rising chorus of concern about how quickly robots are taking away human jobs.

He also cites an Oxford U. study

In 2013, policy makers largely ignored two Oxford economists who suggested that 45% of all US jobs could be automated away within the next 20 years. But today that sounds all but inevitable.

Gates, Musk and Hawking are the smartest humans in the world and I have cited them early and often in my innovation blogs and books. But, no disrespect, but none of them is a full time market watcher. We should take much more detailed studies from Oxford, Gartner (my former employer), McKinsey and other market watchers a bit more seriously.

Unless their studies are flawed.

In researching my recent book, Silicon Collar I found many flaws. Here are a couple in the Oxford study from my book

Nobody appears to have mapped the Oxford report to actual employment trends in the job categories they analyzed. The professors had calculated a high 0.79 “susceptibility to computerisation factor” (with 1.0 being the highest) to heavy truck and tractor-trailer drivers. This, when the U.S. trucking industry says driver shortages could reach as high as 175,000 positions by 2024 (even if the industry adopts autonomous trucks, regulations will likely require a driver as a backup). The professors had assigned an even higher factor of 0.84 to cartographers and photogrammetrists (who deduce measurements from images), which the BLS projects as one of the fastest growing occupations over the next decade. They had assigned a yet higher 0.94 factor to accountants and auditors, whereas hiring at U.S. public accounting firms jumped to reach record levels in 2013–2014.

Similarly, few appear to have asked the Oxford professors whether it is all doom and gloom. What about new jobs from the automation and new digital businesses? J.P. Gownder, an analyst at the research firm Forrester, is one of the few to have analyzed the Oxford work, and he estimated that “new automation will cause a net loss of only 9.1 million U.S. jobs by 2025.” His numbers are well under the roughly 70 million jobs that Frey and Osbourne believe to be in danger of vaporization.

Many of the jobs the Oxford study analyzed require combinations of finger dexterity, crawling capability, visual acumen, social grace, or cognitive and many other human skills. Of course, you can point to individual technologies that can match humans on each skill but show me a systems integrator which has put such a “Frankensoft” machine together for each of the 800 occupations the Bureau of Labor Statistics tracks? And when they do, how long before it matures? (before you answer, check what version of OS you are on after decades of evolution of the PC) And what will it cost to be competitive with a human?

In 2014, Gartner predicted “one in three jobs will be converted to software, robots and smart machines by 2025…New digital businesses require less labor; machines will make sense of data faster than humans can. By 2018, digital business will require 50% fewer business process workers.”

The fact is that Gartner issues hundreds of similar predictions each year and rarely audits them for future accuracy. It usually assigns a probability to them, as an indicator of its confidence in such a prediction, and this statement did not indicate any such hedge.


You can go back every few decades all the way back to the Luddites and you find similar panic attacks. The Luddites, of course, had the ultimate panic attack. They were bands of English workers in the 1810s who destroyed newly introduced machinery, especially in cotton and woolen mills, fearing their jobs would be lost.

Studying the history of automation allows you to calmly assess what I call in this article “circuit breakers” that slow down societal adoption of automation

Agriculture has gradually been automated for centuries and we are still not done as we enter a phase of “precision agriculture” where GPS, drones and other technology allow for highly customized farm care. Ditto with manufacturing where we are moving to a new stage of robotics, wearables, 3D printing and other technology which is allowing cities like Greenville, SC to be reborn from a textile mill town to one which makes BMW SUVs for the world.

UPC scanners which started showing up in grocery stores in the 1970s have decades later not killed checkout clerk jobs. ATM machines and mobile banking have still not killed teller jobs (you may be shocked to hear we still have 90,000 bank branches with human employees in the US, and many times that around the world) Email and e-commerce may have reduced the demand for the delivery of letters, but they have not killed off the U.S. Postal Service. In fact, e-commerce has created an entirely new category of postal jobs related to delivering items ordered online. The robots at the mail marketing company Valpak and those at the distribution centers of Amazon and other companies help keep more than 600,000 postal employees busy.
