Because you can have it review itself and iterate on its own work before showing you. If you insist on reviewing its one-shot output you'll be disappointed, but if you consider its internal work private and only consider its final output, it's different.

Also we're still in the middle of the transformation, clearly the AI we'll have in 5 years will be radically different and better (by some definition of better) than what we see today. It's kind of weird that you'd be disappointed that the world will only be totally transformed in ten years, and not five.
