I will say that a lot of the "full decompilation" projects popping up are honestly crap - some are good, but a lot of them just build something that makes for a good screenshot or promotional video.

I'm not convinced we are actually at the point where something like Photoshop is trivial to rebuild. That involves a lot of manual QA and the expertise in actually knowing how everything should work.

That said, give it 6-12 months and I won't be surprised if they can one-shot "create a future-complete clone of Photoshop, make no mistakes"
