“It's like a wrapper for some APIs, right?”
Don’t be sorry it shows your true colors. The point stands that you continue to step around. Cursor and other tools like it are more than a trivial wrapper but of course you have never used them so you have no idea. At least give yourself some exposure before projecting.
Dropbox is still a $5+bn business. Cursor is still growing, will it work out, I don’t know but lots of folks are seeing the value in these tools and I suspect we have not hit peak yet with the current generation. I am not sure what a service business like a small biz website builder has to do with Cursor or other companies in adjacent spaces.
