I just tried bolt.new. If that’s the latest thing that AI coder can do, we software engineers may have our jobs for at least a few more months.
It is not very usable. Here are the problems:

The separation of AI editor and regular Editor.

If you want to use AI, you go to bolt.new; if you want to have regular IDE stuff, you go to stackblitz.com. This separation is really weird. We know that some tasks are faster with AI, some are faster with direct coding. Are we expected to switch back and forth all the time?

Given a prompt, AI may change multiple files

AI does it so quickly that humans can’t consume all the changes and make sure they make sense.

Cursor has none of the problems above.
