A new MIT report proposes how humans should prepare for the age of automation and artificial intelligence.
- A new report by MIT experts proposes what humans should do to prepare for the age of automation.
- The rise of intelligent machines is coming but it's important to resolve human issues first.
- Improving economic inequality, skills training, and investment in innovation are necessary steps.
1. Increase private sector investment in skills and training<p>The group pinpoints the importance of private sector investment in training employees, especially with the purpose of increasing the upward mobility for lower-wage and less-educated workers. This will particularly affect minority workers, who are overrepresented in this group. The report estimates only about half of employees get training from their employers in any given year. </p>
2. Significantly increase federal funding for training programs<p>The report advocates getting the government to fund training programs that can help lead to middle-class jobs for workers who don't have a four-year college degree. </p>
3. Support community colleges<p>The research team thinks community colleges should be supported by the federal government's money and policies to advance programs that connect employers to the education being received by students. The policies should be aimed at raising degree completion rates at community colleges. </p>
4. Invest in innovative training methods<p>Demonstration and field testing programs that work out new retraining and reemployment ideas should be given particular focus, according to the MIT scientists. </p><p style="margin-left: 20px;">"Innovation improves the quantity, quality, and variety of work that a worker can accomplish in a given time," <a href="https://workofthefuture.mit.edu/research-post/the-work-of-the-future-building-better-jobs-in-an-age-of-intelligent-machines/" target="_blank">wrote</a> the report's authors. "This rising productivity, in turn, enables improving living standards and the flourishing of human endeavors. Indeed, in what should be a virtuous cycle, rising productivity provides society with the resources to invest in those whose livelihoods are disrupted by the changing structure of work.</p>
5. Restore the real value of the federal minimum wage<p>The report spotlights the growing economic disparity between low-paid workers and the rest of society. Compared to Canadians, for example, low-paid Americans earn 26 percent less. Government policy should make sure people in traditionally low-paid service jobs like cleaning, groundskeeping, food service, entertainment, recreation, and health assistance get adequate pay and some economic security. To that end, the researchers propose that the minimum wage should be raised to at least 40 percent of the national median wage. This value should also be indexed to inflation. </p>
6. Modernize and extend unemployment insurance (UI) benefits<p>Several measures are recommended to improve unemployment insurance and extend it to workers that aren't usually covered. The report suggests allowing workers to count their most recent earnings to determine eligibility, determining eligibility based on hours rather than earnings, dropping the requirement that unemployed seek full-time work (because many hold part-time jobs), and reforming partial UI benefits from the states. </p>
7. Strengthen and adapt labor laws<p>Labor laws need to be both improved and better enforced, states the report. Contraction of private sector labor unions makes it harder for rank-and-file workers to bargain for wage growth that matches the growth of productivity growth. How workers are represented needs to be innovated as much as the technologies. Current U.S. laws "retard the development of alternative approaches," write the researchers. For example, due to racial politics during the New Deal, sectors of the American workforce like domestic workers and agricultural workers are unable to participate in collective bargaining.</p>
8. Increase federal research spending<p>In a proposal aimed at fostering innovation and making sure its benefits are experienced by workers, the MIT group thinks it's key to increase government spending on research, especially in areas not addressed by the private sector. These tend to involve longer-term research that addresses the social impacts of new technologies, zeroing in on major national problems, climate change, human health and similar larger research topics. Investing into research on human-centered AI, collaborative robotics and the science of education should be a part of this approach.</p><p>Small and medium-sized businesses should receive targeted government assistance to allow them to increase productivity via the new tech, advises the MIT team. </p>
9. Expand the geography of innovation in the United States<p>Innovation is increasingly "concentrated geographically," think the researchers. For a country that has so many universities, entrepreneurs, and workers that are spread throughout, the benefits of innovation should be made available not only to more workers, but also to more of the country's regions. Each state can have its own Silicon Valley.</p>
10. Rebalance taxes on capital and labor<p>Innovation is necessary in the tax law as well, according to the report. It's important to change the manner in which the current tax code "unduly favors investments in capital" by eliminating accelerated depreciation allowances, applying corporate income tax equally to all corporations, and instituting an employer training tax credit.</p><p><a href="https://workofthefuture.mit.edu/research-post/the-work-of-the-future-building-better-jobs-in-an-age-of-intelligent-machines/" target="_blank">Read the full report here.</a></p>

New insights into the role of water vapor may help researchers predict how the planet will respond to warming.
Just as an oven gives off more heat to the surrounding kitchen as its internal temperature rises, the Earth sheds more heat into space as its surface warms up. Since the 1950s, scientists have observed a surprisingly straightforward, linear relationship between the Earth's surface temperature and its outgoing heat.
But the Earth is an incredibly messy system, with many complicated, interacting parts that can affect this process. Scientists have thus found it difficult to explain why this relationship between surface temperature and outgoing heat is so simple and linear. Finding an explanation could help climate scientists model the effects of climate change.
Now scientists from MIT's Department of Earth, Atmospheric and Planetary Sciences (EAPS) have found the answer, along with a prediction for when this linear relationship will break down.
They observed that Earth emits heat to space from the planet's surface as well as from the atmosphere. As both heat up, say by the addition of carbon dioxide, the air holds more water vapor, which in turn acts to trap more heat in the atmosphere. This strengthening of Earth's greenhouse effect is known as water vapor feedback. Crucially, the team found that the water vapor feedback is just sufficient to cancel out the rate at which the warmer atmosphere emits more heat into space.
The overall change in Earth's emitted heat thus only depends on the surface. In turn, the emission of heat from Earth's surface to space is a simple function of temperature, leading to to the observed linear relationship.
Their findings, which appear today in the Proceedings of the National Academy of Sciences, may also help to explain how extreme, hothouse climates in Earth's ancient past unfolded. The paper's co-authors are EAPS postdoc Daniel Koll and Tim Cronin, the Kerr-McGee Career Development Assistant Professor in EAPS.
A window for heat
In their search for an explanation, the team built a radiation code — essentially, a model of the Earth and how it emits heat, or infrared radiation, into space. The code simulates the Earth as a vertical column, starting from the ground, up through the atmosphere, and finally into space. Koll can input a surface temperature into the column, and the code calculates the amount of radiation that escapes through the entire column and into space.
The team can then turn the temperature knob up and down to see how different surface temperatures would affect the outgoing heat. When they plotted their data, they observed a straight line — a linear relationship between surface temperature and outgoing heat, in line with many previous works, and over a range of 60 kelvins, or 108 degrees Fahrenheit.
“So the radiation code gave us what Earth actually does," Koll says. “Then I started digging into this code, which is a lump of physics smashed together, to see which of these physics is actually responsible for this relationship."
To do this, the team programmed into their code various effects in the atmosphere, such as convection, and humidity, or water vapor, and turned these knobs up and down to see how they in turn would affect the Earth's outgoing infrared radiation.
“We needed to break up the whole spectrum of infrared radiation into about 350,000 spectral intervals, because not all infrared is equal," Koll says.
He explains that, while water vapor does absorb heat, or infrared radiation, it doesn't absorb it indiscriminately, but at wavelengths that are incredibly specific, so much so that the team had to split the infrared spectrum into 350,000 wavelengths just to see exactly which wavelengths were absorbed by water vapor.
In the end, the researchers observed that as the Earth's surface temperature gets hotter, it essentially wants to shed more heat into space. But at the same time, water vapor builds up, and acts to absorb and trap heat at certain wavelengths, creating a greenhouse effect that prevents a fraction of heat from escaping.
“It's like there's a window, through which a river of radiation can flow to space," Koll says. “The river flows faster and faster as you make things hotter, but the window gets smaller, because the greenhouse effect is trapping a lot of that radiation and preventing it from escaping."
Koll says this greenhouse effect explains why the heat that does escape into space is directly related to the surface temperature, as the increase in heat emitted by the atmosphere is cancelled out by the increased absorption from water vapor.
Tipping towards Venus
The team found this linear relationship breaks down when Earth's global average surface temperatures go much beyond 300 K, or 80 F. In such a scenario, it would be much more difficult for the Earth to shed heat at roughly the same rate as its surface warms. For now, that number is hovering around 285 K, or 53 F.
“It means we're still good now, but if the Earth becomes much hotter, then we could be in for a nonlinear world, where stuff could get much more complicated," Koll says.
To give an idea of what such a nonlinear world might look like, he invokes Venus — a planet that many scientists believe started out as a world similar to Earth, though much closer to the sun.
“Some time in the past, we think its atmosphere had a lot of water vapor, and the greenhouse effect would've become so strong that this window region closed off, and nothing could get out anymore, and then you get runaway heating," Koll says.
“In which case the whole planet gets so hot that oceans start to boil off, nasty things start to happen, and you transform from an Earth-like world to what Venus is today."
For Earth, Koll calculates that such a runaway effect wouldn't kick in until global average temperatures reach about 340 K, or 152 F. Global warming alone is insufficient to cause such warming, but other climatic changes, such as Earth's warming over billions of years due to the sun's natural evolution, could push Earth towards this limit, “at which point, we would turn into Venus."
Koll says the team's results may help to improve climate model predictions. They also may be useful in understanding how ancient hot climates on Earth unfolded.
“If you were living on Earth 60 million years ago, it was a much hotter, wacky world, with no ice at the pole caps, and palm trees and crocodiles in what's now Wyoming," Koll says. “One of the things we show is, once you push to really hot climates like that, which we know happened in the past, things get much more complicated."
