The other way this illustrates a massive problem is the idea that we are supposed to be impressed by this functionality. I'm not speaking specifically of the functionality that the grandparent poster used in his example, but just the general idea, for example: "Look at this classic console emulator, running in a webpage! (At 80% of the speed it would have run on a circa-1990s 90 mhz Pentium if it were a a native app!)" To be clear, it is impressive when people create such things given the constraints, but (even ignoring the fragile compatibility problem between different browsers) when the platform you are using makes doing something that was impressive almost 20 years ago impressive (again) today, I'm not sure that's something we should all be that proud of as an industry.
