I'd be quite happy as a citizen of The Culture.
But, on a more serious note, or more realistic, I find it vaguely insulting that you think that so many of us are just so shallow we'll not figure out how to live meaningful lives in an AI dominated future. The world is already meaningless. Some people live in the US, get tech jobs and live lives of almost indescribable luxury compared to someone born in South Sudan. There are beggars on the streets of most African countries, who are deformed of malnutrition and suffering in pain. There are children who will never know true happiness, and die in misery.
It's all fucking senseless and nasty, and as someone who originated from such a poor country it is infuriating to see spoiled developed world complaints sometimes.
We live, suffer, die. Some suffer less, some a lot more. We find out own meaning somehow, in this brief weird experience that we perceive as conscious life.
If an AI can bring a few billion 3rd world people out of misery, I don't think I'm going to shed tears if that means you have to somehow "find meaning" outside of a high paying tech job.
