With AMP, you basically get guard-rails to prevent your team of junior engineers from making your mobile pages too slow in exchange for increasing The Google's monopoly power. :D If I remember correctly, with AMP, you have to use their web components, and you have to pass their validator or pages won't be listed or cached at all. AMP is not really innovative in the slightest. One can easily serve pages faster than an average AMP page if they wanted to. The businesses that see engineering as a necessary evil are not properly incentivized to care about page performance, and are sometimes only prodded into doing so if a giant like The Google tells them to. Management tells their programmers that they read an article about AMP and that it makes pages load faster and reaches a wider search audience by caching and cutting out unnecessary crap; the more seasoned programmers think "Yeah, no shit – I've been trying to tell you... but I'll spend time rebuilding pages for AMP because I get paid the same either way."

This is incorrect. You cannot beat prerendered. It does not make sense to implement AMP for people visiting your website directly. AMP is for link aggregators like search engines, news aggregators, and social media websites.
