I've had the same thought, and I'd love to see an analysis of spreadsheet software adoption and (e.g.) financial sector employment to situate LLMs in their proper historical context. A brief glance at FRED data doesn't seem to point to any big changes in the job growth rate in that sector, but there's obviously too much exogeneity there to really say.

As an LLM researcher, I think a large hurdle is the set of last-mile problems like those that have plagued self-driving cars. Yes, stakes are comparatively much lower when automating a job posting, but correctness matters.
