1. This gets trotted out constantly but this is not some known constant about how capitalist economies work. Just because we have more jobs now than we did pre-digital revolution does not mean all technologies have that effect on the jobs market (or even that the digital revolution had that effect). A tool that is aimed to entirely replace humans across many/most/all industries is quite different than previous technological advancements.
2. This is outdated, life is NOT better now than at any other time. Life expectancy is going down in the US, there is vastly more economic inequality now than there was in the 60s, people broadly report much worse job satisfaction than they did in previous generations. The only metric you can really point to about now being better than the 90s is absolute poverty going down. Which is great, but those advancements are actually quite shallow on a per-person basis and are matched by declines in relative wealth for the middle 80% of people.
3. ??? What kind of AI are you talking about? LLMs have only been interesting to the public for about a year now
