There's no real reason to think that AI is unique among all the livelihood destroying technologies that have come before in that it will destroy jobs without opening new ones in their place. It seems to me fighting the march of technology is akin to fighting the tides. Yes, you can build sea walls, and in the modern age, we literally can hold back the tides. But at the cost of ever increasing expenditures of time, resources and/or money. We could spend our resources trying to preserve livelihoods whose time has come and gone, but why specifically these jobs and not say, coal miners, farriers, lamp lighters, whalers, operators, computers, thread spinners or any of the multitudes of other jobs that technology is obsoleted? If we think on all the jobs that have been lost to technology over the decades, how many of those jobs do we think would have left the world in a net better place had we eliminated the technology that obsoleted the job and kept all the people employed in those positions where they were. Are people scared for their livelihoods because the technology will destroy the job, or because societies tend to spend all their energy trying to fight the technology instead of helping people find new jobs and livelihoods and the technology always eventually wins?
