The chances are that the automation enabled by LLMs like GPT-4 and beyond, will erase billion of jobs in the world, no further than in a couple of years. This time it won't be a warm-up time, like it happened with previous technological evolutions.
But, most societies will be mostly full of unemployed humans, and that will also probably cause some big changes (the ones required for the meat bags to keep eating, having health, homes, etc.), as big as the ones caused by AI revolution.
The question is what changes will happen and how societies will rewrite themselves anew, to overcome the practical full absence of open positions to earn an income.
