Perfect? Who said anything about perfect data? I said actually fact checked data. You keep movimg the bar on what possible as an excuse to not even try.
They could indeed build models that worked on actual data from expert sources, and then have their agents check those sources for more correct info when they create an answer. They don't want to, for all the same reasons I've already stated.
It's possible, it does not "doom" LLM, it just massively increases its accuracy and actual utility at the cost of money, effort and killing the VC hype cycle.
Basically 48 hrs between muscle groups. Mon - Wed - Friday is a reasonable pace if you do an "all in one" routine. If you want to do daily lifting workouts, you need to rotate arms/legs/core then repeat.
OP, it seems counter-intuitive to workout less to improve, but you have to realize that you gain muscle by straining and overworking current muscle. To build and repair, the muscles need rest, nutrients and time. If you don't give it to them, they can't build up.
Sleep, time and food are all as important as how much and how often you lift weights.
