Innovation outside of rich coorps will end. No one will visit forums, innovation will die in a vacuum, only the richest will have access to what the internet was, raw innovation will be mined through EULAs, people striving to make things will just have ideas stolen as a matter of course.

The original Yahoo doesn't exist (outside archive.org), but I'm guessing would be a keen person or two out there maintaining a replacement. It would probably be disappointing, as manually curated lists work best when the curator's interests are similar to your own.
What you want might be Kagi Search with the AI filtering on? I've never used Kagi, so I could be off with that suggestion.
