As I pointed out in a different comment, the Internet at least was (and is) a promise of many wondrous things: video call your loved ones, talk in message boards, read an encyclopedia, download any book, watch any concert, find any scientific paper, etc etc; even though it has been for the last 15 years cannibalised by the cancerous mix of surveillance capitalism and algorithmic social media.
But LLMs are from the get-go a bad idea, a bullshit generating machine.
