You talk like that because you're a front web developer and that's your bread and butter. There are tons of other areas (even in computer science) where you are out of your bubble and you know nothing about.

Similarly, there are people who don't work on websites, writing javascript, in fact they think they think those people are dumb monkeys who can't even make their stuff work on all browsers.

They don't care about latest features, in fact they prefer browser being a dumb tool to view websites not a replacement for an OS.
