AMP pages are still there if you are still using Google on mobile.

I switched to duckduckgo on my phone for now.

I'm thinking about building a search page where the query goes to my home desktop computer where I run headless Chrome to scrape results from all the search engines and then forward them back to my phone. Unfortunately, Apple will not fucking let me use a custom search engine in Safari on the iPhone, probably because they're in cahoots with Google and China to bring about a new world order where nobody has any freedom whatsoever. xD
