What can flash do that modern browsers can't?
Nothing, of course. Anything that could be done with Flash in its heyday can be done better (in several senses) with modern tools. But that’s not what we’re talking about, is it? We can ask what’s actually being done in web design these days… and who’s doing it. If you’re old enough to remember the period from the late ’90s to the mid aughts, think about your friends who were putting all kinds of wacky, creative page…
We know there are better technologies security wise and performance wise. It's not always about what is 'technically' better rather than something that people enjoyed using and opened the door to creative personalities for the web. There is a time and a place for both and I think there has been neglect for the other side of the brain.
