  Because when you make the technology better, you can do one of two things with it: you can make the videos load faster, or you can make them look better when they load. You can’t do both, and if you have better-looking video, everybody notices. If you have faster-loading video, only some people notice, so most of the time companies choose better-looking video instead, and we still have to wait for it to buffer.
