While I agree with the gist of that article/presentation, it's more on the silly side compared to many other more detailed and accurate pieces about the growing weight of the modern web.

While blocking ads will help some (and certainly some ad providers have gone way too far with their bandwidth/cpu requirements), the web is just a richer media experience than before. The mainstream does not just want text and 80-90% of the page weight ends up being images, even on that article itself. There are other advancements like HTTP/2 and modern CDNs and better image formats like FLIF that will solve this problem much more effectively without going back to a textual world.

Still don't see what any of this has to do with HTTPS encryption everywhere though...
