"Imagine you design a website, and then Google changes their ranking algorithm to provide preferential treatment to AMP pages. You see that your ranking has decreased, and so you implement AMP.

"A few months later, Google announces that they will provide preferential treatment to websites that have progressive web apps, and you see that your website falls in the rankings to the second page. Once again, when Google asks you to jump and dance like a moron, you flail your arms and repeat that you are not worthy."
