We don't know if it will take the form of a net drop in headcount at all, or if white collar labor will be broadly replaced with the same headcount of low paid fungible AI operators.

What work do you imagine a "low paid fungible AI operator" would perform, out of curiosity?
Wanting to be ahead of the next hype-cycle narrative is plenty for a lot of speculative investors.
