What does labor-saving technology do to workers? Does it make them poor? Does it take away their jobs?
Let's review!
First: Most papers do support the idea that technology takes people's jobs.
This needs qualified.
Most types of job-relevant technology do take jobs, but innovation is largely excepted, because, well, introducing a new innovation tends to, instead, give employers money they can use to hire people.
But if technology takes jobs, why do we still have jobs?
Simple: Because through stimulating production and demand, it also reinstates laborers!
This is supported by the overwhelming majority of studies:
This reinstatement effect is largely consistent across types of technology, with innovations still looking a bit odd.
That is the weirdest category of technology besides "other", so roll with it.
Now the operative question is, if workers lose their jobs and end up reinstated in other jobs, what happens to their incomes?
Well, technology introduction tends to boost incomes!
Across types of tech, this result is pretty consistent: studies agree, technology makes us richer!
But, you might ask, whose income is boosted? Because if reinstatement affects far smaller numbers of workers than replacement, some people might still be getting shafted.
Well, the net employment effects of technology are highly ambiguous:
If we look across types of technology the picture I mentioned above for innovation-style technology shows up again: many studies suggest it's good for employment.
The reason impacts on net employment are so ambiguous is because they really have to be qualified.
For example, in general, when robots cause manufacturing employment to fall, there's a compensatory effect on service-sector employment that's at least as large in magnitude:
What makes that impact so interesting is another way it's qualified: It's smaller in industries more at-risk of offshoring.
In other words, industrial robots save American jobs from going overseas.
Industrial robots also contribute directly to reshoring. In other words, when Americans buy robots to do their manufacturing, Mexicans lose their jobs.
The welfare impact for domestic workers is positive. Not so for Mexicans, but that's just how things go.
Overall, labor-saving technology is clearly good, and the longer we delay adopting it, the poorer we will be relative to the world in which we picked it up immediately.
I'm not going to rig an ongoing poll by linking directly to it, but I will say that >90% of respondents so far were wrong:
The answer is climate🧵
Anatomically modern humans first appeared around 200,000 years ago.
After a few false starts, the dawn of man took place with a series of dispersions out of Africa about 60,000 years ago.
By 40-50 thousand years ago, humans had made it most places, and by 10-20, to the Americas
Practically all of that time dispersing took place as hunter-gatherers.
Specifically, nomadic hunter-gatherers. The real advent that made agriculture possible wasn't changing the mode of subsistence per se, but changing to sedentism.
I just read one of the most interesting climatic reconstructions I've ever seen.
This one gives us temperature records for the last 485 MILLION years.
The reconstruction is based on a lot of different methods, but the one that really stood out was the part where they leveraged the shell chemistry of single-celled organisms' fossils.
Wild that this is possible and someone thought of it!
With these little organisms' data in hand, it's possible to obtain a high-fidelity picture of the past in which we emerged on the global scene.
That picture is one that averages much, much colder than basically any other period in time.
I suspect "The Sort" can greatly increase your exposure to time-wasting incompetence🧵
The obvious example of how The Sort exposes you to incompetence is that nowadays, competent people don't go into the public sector all that often.
This is a mixed bag: while the government is a poor use of human capital, it needs some to avoid holding back the rest of society.
There are also a lot of fairly menial service sector jobs that you'll run into all the time, and these are less obviously, but no less problematized by The Sort.
