Every one of them raised the floor very quickly. The increase in travel made way better quality of life available to way more people. But this isn’t the Middle Ages. You don’t need to enslave yourself to someone for a decade before you can get a new job.
LLMs can’t do anything. “AI” will eventually replace jobs, but LLMs (the current “AI” everyone is spending through the nose on) can’t actually do anything.
Self driving will be a great thing that saves lives exactly as quickly as it’s implemented. It’s not really connected at all to the current “AI” LLM bubble, though, because again, LLMs don’t work.
The last decade has been those “middle class” jobs moving to China/India and providing way more of them with jobs that pull them from starving to not starving.
You can debate policy stuff of offshoring and whatever, but globalization isn’t removing jobs. It’s moving them. It’s completely separate from technology making labor more efficient.
