MIT Future of Work task force finds robots not destroying jobs

A sprawling new report makes the case that automation and AI won’t lead to widespread job destruction anytime soon.

Why it matters: Technological advances in AI and automation will have an enormous impact on the workforce, but it may take decades for those effects to be fully felt. That gives business leaders and politicians a last chance to change labor and education policies that have left too many workers locked in low-quality, low-paying jobs.

What’s happening: On Tuesday, MIT’s task force on the Work of the Future released its final report, coming to the conclusion that the immediate effects of automation on work were overhyped and overshadowed by longer-term political trends that have allowed an increasingly unequal share of economic growth to be captured by the well-off.

  • “If we deploy automation in the same labor market system we have now,” says David Mindell, an engineer at MIT and one of the report’s main authors, “we’re going to end up with the same results” — an ever-expanding divide between the haves and the have-nots.

Details: In contrast to more pessimistic predictions, the task force found automation and AI currently had the same effect on total job numbers as past technological shifts — some jobs were being destroyed while others were being created, even as overall employment generally kept rising.

  • The result is a picture of jobs that looks very different than it did decades ago — 63% of jobs in 2018 didn’t even exist in 1940 — but ultimately one where work remains available.
  • It’s possible that one day truly general AI and highly capable robots might be able to do whole classes of jobs more efficiently than human beings, but “the adoption and deployment of these technologies take time, and we’re just at the beginning of a 30- to 40-year cycle,” said Elisabeth Reynolds, the executive director of the task force, at an event Wednesday.

Be smart: The reality is that the human brain — and just as much, the human hands — are still far more adaptable and flexible than any machine, no matter how narrowly intelligent.

  • “We were promised driverless cars by 2018, and they’re still not here,” notes Mindell. Rather than design and build a technology that can mimic a complex human action — like those of the more than 3 million commercial drivers in the U.S. — it’s cheaper and more effective to simply hire a human.
  • For now, the effect of automation and AI — and digital technology more broadly — has been one of augmentation rather than replacement, making individual workers more productive by automating routine tasks.

Yes, but: The task force argues the fruits of that productivity growth have not translated into broad income increases not because of technology but because of a fundamentally broken labor market.

  • Between 1948 and 1978 productivity and average wage growth for production and nonsupervisory workers rose in near lockstep, but since then, median wages have stagnated even as technology-aided productivity has continued to rise.
  • While workers around the world grapple with the effects of technology, Americans fare worse — the task force found adjusted gross hourly earnings of lower-skill workers in the U.S. averaged $10.33 in 2015, compared to $24.28 in Denmark, $18.18 in Germany, and $17.61 in Australia.

The response to these trends should be less technological than political, the task force urges.

  • The U.S. needs to modernize its labor policies: upgrading unemployment insurance, improving collective bargaining rights and raising the minimum wage.
  • Workers — especially the more than 60% of adults who lack a four-year college degree — need help in reskilling and retraining for the future, including on the job.
  • The federal government should reverse the long-term decline in its contribution to R&D in order to “continue the innovation cycle,” says Mindel.

The bottom line: The future many American workers face as automation filters in is not one where work is scarce, but where work is low paying and unsatisfying.

身為一個文青(嗯),會對文青女神張懸(早改名叫安溥啦)在今年與VIVE Originals與合作的虛擬實境MV《蘚的歌唱》感到好奇,也是一件相當合理的事。 只不過,《蘚的歌唱》不僅是一支VR作品,專注於實驗並拓展虛實邊界的VIVE Originals,把這首短短幾分鐘的歌拍成了「微型演唱會」。視覺呈現固然重要,但視覺之外的互動及感官體驗,才是這支作品的重點。因此,我終於在文策院的創意內容大會(Taiwan Creative Content Fest; TCCF),體驗到了《蘚的歌唱》。 《蘚的歌唱 : 音境漫遊》有夠美的。(來源:viveoriginals) 用最淺顯直白的文字來描述TCCF版本的《蘚的歌唱 : 音境漫遊》,其實就是「VR+體感椅」,而為何以「演唱會」形容之?深入一點說,它是體感椅與影像畫面調度的結合。 《蘚的歌唱》裡的VR畫面當然美得嚇人,安溥一貫碎念卻詩意的歌聲,本就是意識流的表現,而她的肢體動作,搭上神秘主義的光影和異世界的場景切換,充分表現音符的情緒流動,讓人在她意識宇宙的每一個小碎片中愜意穿梭。懸臂攝影機般的畫面調度,透過體感椅的即時連動,讓我彷彿看著4DX的VR電影,讓這趟VR體驗進入了與過往不同的另一個境界。
