I understand what the author is saying but it sounds like wanting tech for tech's sake. If the user doesn't care, then does it matter that sites are slower? And if it matters, why hasn't someone come along and done something better like the author suggests? Surely this trend in tech performance has been going on for so long that someone could be doing something about it?
