The ecosystem surrounding web standards make hard almost every use-case Flash had. The web standards and its implementation is a friggen mess. Try doing anything non-trivial with audio and you’ll see what I mean.
Instead of slow animated restaurant website we now have blogspam recipe sites or slow electron apps.
The web standards at the time could barely vertically centre a div, and many of the proponents of web standards had the gall to say the web standards would supersede Flash.
The problem was that creative people were intruding into the space of old school software developer mentalities and “standards” people. Flash devs got paid extremely well, were highly collaborative, and executed exceptionally fast. But they weren’t “doing it the proper way” and for some reason the software/tech industry at large needed to show Flash how it was meant to be done. No one yet figured out how to properly centre a div or agree on what was restful, but knew for sure Flash was doing it wrong because the <video> tag was now only 4 short years away from viable browser penetration.
And now we finally made it. The 2d canvas context can fill paths, you can loop an audio file, you can even centre divs. You just gotta duck tape all that garbage together, manually through code, forget about animation authoring, in a dry as heck Node.js tooling ecosystem, and spend your nights replaying arguments you had with your co-workers about linting rules.
The infrastructure and tooling should make the easy path relatively benign.
