they're an upgraded version of self-executable zip files that compresses knowledge like mp3 compresses music, without knowing exactly wtf are either music nor knowledge

the self-execution is the interactive chat interface.

wikipedia gets "trained" (compiled+compressed+lossy) into an executable you can chat with, you can pass this through another pretrained A.I. than can talk out the text or transcribe it.

I think writing compilers is now an officially a defunct skill of historical and conservation purposes more than anything else; but I don't like saying "conservation", it's a bad framing, I rather say "legacy connectivity" which is a form of continuity or backwards compatibility
