I genuinely think Google's success is its own undoing.
If everybody had carried on making sites in the same way they did when Google came out, the results would still be good.
Bit they didn't. There's gold in them thar hills, and now SEO and generated bullshit are a way to make money, while Google's algorithms seem easy to game if you have the resources to do so.
There's like a hundred large companies doing this, and if you blocked all their sites in the Google results it'd give results similar to Kagi and other flavour of the month search engines.
