Flash and its tooling was undistinguishable - they did not existed one without another. It was not some separate thing made by someone else. It was made by Adobe, from the start. I think it matters - flash itself was designed so that making great tooling was possible from the start. Web standards are simply not designed for that. They stand in the way, basically.

> why hasn't anyone created tooling on par with what existed for "flash developers" that instead of generating actionscript to be executed by the flash plugin, generated javascript, webassembly, interaction with canvas elements and webgpu.

First, I think there is aspect of "javascript, webassembly, interaction with canvas elements and webgpu" being quite hard to generate in a way that would achieve the same as flash did. As API, they comparatively sux although they are improving.

What you suggest is much harder then it looks like and involved technologies are not making it easier.

It was not made by Adobe from the start. It was made by FutureWave which was bought out by Macromedia who continued to develop it years before they in turn were bought by Adobe.
