I want this too, but I think an often understated aspect of this issue is that by this point Google has absolutely trashed the web of that era. In these threads people will say "the content you want isn't out there, it's all on social media now" -- and they're largely right, but I think Google is the party most responsible for mutilating the web to the state it is in now, and users fled to social media partly because it seemed like a safe haven.
What we need is a concentrated effort to rebuild the web. Take the best parts of what we've learned and combine with the best parts of what we've left behind and try to build something better, for humans, not for advertisers and hyper-capitalists.
That will take time, energy, and people who remember what we lost and believe we can build something better. A better search engine alone is not enough.
