We're doing that in my office, forced Cursor use. A good chunk of the "edited by AI" lines in my history were just auto-completing about the same as a traditional intellisense-alike would do (and actually Cursor doesn't seem to supply that, which is frequently annoying and wastes my time, in particular when I need to make sure it hasn't hallucinated a method or property on an object it should be able to "see" the definition of, which it does constantly; IDK maybe there's a setting somewhere, but I don't have to fiddle with settings in vanilla VSCode to get that...)
It's actually kinda useful in some cases, but the UI is terrible and it needs to integrate much better with existing tools that are superior to it for specific purposes, before I'll be happy using it. I'd say the productivity gains are a wash, for me, so far. Plus it's entirely too memory-hungry, I'd just come to accept that a text editor takes a couple GB now (SIGH), and here it comes taking way more than that.
