The bitterest lesson is we want slop (or, "slop is all you need")
Maybe you can recognize that someone else loves a certain kind of slop, but if LLMs became vastly more intelligent and capable, wouldn't it better for it to interact with you on your level too, rather than at a much higher level that you wouldn't understand?
If you used it to make you a game or entertain you with stories, isn't that just your own preferred kind of slop?
If we automate all the practical stuff away then what is left but slop?
