> not really a fan of resurrecting Flash
Sounds like you're not a fan of resurrecting Flash Player. The previous poster (GP) was pining for a resurrection of Flash. You're talking about different things.
I thought that still exists? Adobe renamed "Flash Professional" to "Adobe Animate", and they're continuing to update it.
After Effects overshadows it for animation and Animate's "interactive application development" story is bloated and crufty. It's not adapted to the present-day software+hardware ecosystem like Flash&Player were in the 90's/00's -- and it never will be.
Agreed! Flash is dead for a reason, and that reason — while manifold and complicated and political and commercial — really boils down to Flash Player.
Back to OP's claim: "Flash needs to come back". I believe they're really pining for (because I pine for) "a creative environment where design, animation, and code coexist — and where every project can be deployed to any device." That was the fulfilled promise of Flash&Player in the 90's/00's.[1]
It will look technically different next time around (WASM? Native mobile targets? Native desktop targets? Modern collaboration/version control?), but I firmly agree with OP that creative environment needs to happen — will happen — again.
[1] Incidentally, that's the presently fulfilled promise of Unity3D for games.
