People are still figuring out how to use LLMs/AI and considering how feelings based and hard is to reproduce many of the results people get, a lot of the improved approaches are basically at "trust me bro" reliability.

TBH i expect it'll take several years before people largely settle on what works good and what works bad (or doesn't work) and that's assuming things wont chance in a massive way during that time.

And this isn't really anything new, people rarely come up with some new way of programming and have everyone learn and understand best uses from the start - it takes years (and that is assuming everyone will agree that'd be something worth bothering about).
