You won't see AMP if you switch search engines.
Surprising how little I've noticed the change, after using Google Search for over 15 years. I try queries on google.com maybe once or twice a week if I don't find what I'm looking for on DDG. If it's anything media or product related, I feel like I'm on an old, crowded MySpace page. DDG feels more like the old Google.
Also, links in the Twitter app default to AMP as well.
