LLMs don't upend anything about labor theory, good grief. Technologists really have no concept of history beyond their own lives do they?

Labor saving/efficiency devices have been introduced throughout capitalisms entire history multiple times and the results are always the same; they don't benefit workers and capitalists extract as much value as they can.

LLMs aren't any different.

Labor replacing devices means nobody works in those fields anymore. If AI can do this for every field, nearly no one will need to work in any field. We'll have a giant fully automated resource-extraction machine.
