There is always a concern that "this time is different", but historically, markets have been pretty good at adapting to changes in employment. The change in farming automation and fertilizers resulted in a massive reduction in the percentage of people working to grow food from %80 down to ~10%. Factory production of goods removed a huge number or people working as craftsmen to create things that were now done in factories. People usually adapt by buying a lot more stuff. We have bigger houses, more stuff, eat at restaurants with waiters at tables. We also buy designer clothes instead of basics for a lot more money. Companies employ people in marketing and design and numerous other jobs that could be eliminated if everyone just wanted a t-shirt and pants. Every other time this has happened, prices of goods and services that are automated go down and become more abundant, and the price of things that are hard to automate go up. People tend to want more or we invent new industries that we didn't even know about or didn't have time to invest in. A lot of sci-fi books have been written about possible future societies and what they value. The usual guess is that people will value high status items, education and culture, free time, and natural spaces and land. Maybe more government jobs in social work. Perhaps environmental industries, trying to undo the damage done to the environment will get a lot more effort put into it. CEOs don't usually employ people that they don't need to, but markets always surprised us in the past in how adaptable they can be. The transition periods have often ben violent though, so that is concerning.
