To quote Pinsplash, fittingly a Half-Life/Source engine modder:
Some have said I should avoid saying AI to avoid confusion with machine learning.
No. NPC AI may not actually be artificial intelligence but nothing in machine learning is true artificial intelligence either and it was our word first. "Our" being gamers. I will not concede any bit of language to dumb-ass tech bros.
It has been a few years since I last used Plex but I always liked their interface, their tech stack is fairly modern, they have apps for pretty much every device, their title matching for content works really well and there was not much wrong with it back in the day other than it lacking local authentication.
I switched over long ago when they started pushing streaming services to my users that I couldn't deactivate server side.
