This has absolutely nothing to do with AMP. May I remind you that slow Internet connections are not a new phenomenon. Try browsing the web on a 9600 baud modem. The means for solving this problem (content negotiation, carefully crafted pages, CSS media selectors) have existed since the dawn of the web, and AMP is a terrible solution that carries the collateral damage of obscuring the URL/source of the original resource and hijacking the presentation of the page.

Slow internet connections have existed for quite a while, indeed. But websites were smaller back then - they didn't load a 300 kB JS file just to hide a few elements.

A slow connection combined with huge websites are practically unusable.

Yes, this is the ideal solution - people adopt saner (and smaller) web development. But that is uncontrollable and, frankly, I don't see it happening.
