That generation will say "How on earth people could do this without AI", just like we have said "How on earth people could do this without the internet".
I gave an LLM recently a job of analysing past sessions to estimate how much time it would take a human to do the jobs requested.
Ingesting 600k word document and drawing conclusions/patterns from it is something I routinely give to Terra. It would take a human 33h non stop to read it. But finding patterns with good precision - personally I wouldn’t be able to.
