Do you think it's technically possible to get something on the level of Photoshop with performance that is, at least, acceptable enough, in the browser? Using asm.js I suppose?
I don't see why not. I won't make any guesses about a timeline, but it seems inevitable to me that it will happen at some point or another. Current technologies allow you to do quite a bit locally and it might even make sense to offload heavy expensive operations to a server instead.
Ah, sorry, I meant to ask if you think it's currently possible with asm perhaps, considering that we can already do quite a bit of heavy stuff in js right now. I have no doubt over time it will be doable, I'm just curious if we might already be there (purely technically, of course, I can imagine we might not have the right tools to actually pull it off right now).
