The best years of YT before 2017, there was an advanced maker and DIY tech culture revolving around people sharing projects and content just to share it. That died. This all pro CC thing has an up side to some extent, but it also lobotomized YT. Peertube might eventually get to the same kind of utility level, but it needs a lot of time and momentum to get there.
I won’t touch the proprietary junk. Big tech “free” usually means street corner data whore. I have a dozen FOSS models running offline on my computer though. I also have text to image, text to speech, am working on speech to text, and probably my ironman suit after that.
These things can’t be trusted though. It is just a next word statistical prediction system combined with a categorization system. There are ways to make an LLM trustworthy, but it involves offline databases and prompting for direct citations, these are different from Chat prompt structures.
