Totally true -- as I see it, in the year 2015: The big problem isn't HTML5 itself, but what people make in it. Most of the crap HTML5 sites out there are made by graphical designers who have no knowledge about programming, and typically only test their creations in isolation on their own machines. When that thing is then released, it is actually displayed on some webpage together with lots of other HTML5 elements and other HTML5 ads, and the whole thing slows to a crawl because none of it was optimised. A good HTML5 programmer can make very good HTML5 movies that don't perform like crap, but good HTML5 programmers are very rare. A lot of people hate HTML5 because of all the low-quality crap that is made with it, and shoved down people's throats through websites, but if you replace HTML5 with something else, you can bet your life that there will still be a lot of low-quality crap, made by non-programmers, that will be shoved down your throat and slow down your browsing experience.
