That's the original "Yahoo Directory", which was a manually curated page.

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.
