All of it ?!?

I remember the time when pc fans hearable meant 95% that i opened a web page with a flash component by mistake...

Heh, I’ve used that test to guess if someone was running npm.

The flash runtime was pretty efficient but the authoring tools were so easy to use that anyone could produce "working" abominations filled with the most good awful code that got the result they wanted.

I guess there is nothing wrong with javascript either?

Humanity has proven it can't handle anything else than static pages. Then the developers themselves have to pay for their bloat rather than the users.
