But I don't think the let's say "other deltas" that are now keeping other high-powered apps from becoming web apps are moving at all. You can check my other comments in this thread for more details, but a specific point I'm making with the original comment is that there are other areas the Figma hasn't dented at all that prevent more powerful apps from being adapted to the browser. And that the fact that design no longer needed those features is what paved the way for its success.
Figma as part of an app family, is way way more similar to Google Slides (i.e., office suite) than it is to Photoshop (i.e., "professional" software).
