Without Flash the current web tech stack might look different
I think what Flash (the program) really excelled at was giving creators the ability to draw, animate and program interactive objects, all wrapped in a single neat package. I would contest that no other software, even today, has come close to being able to do these three so seamlessly at once (Really, I encourage you to try to name one!)Sure, when it came down to it you can say it had poor performance, security, filesize bloat (all things that were fixable or you could work around). But in reality, it allowed for developers to create amazing things in a fraction of the time it would take in any other environment.As for myself, I've moved on to OpenFL and Haxe. It's fast, it's lean, it's cross-platform, it's open source... but it's still not the same.
