I can/have done this without AI and it tends to be disasterous. Management declares we need X fast. Okay, we can build that really fast, but it won't scale. Management says fine, just build it. We do. Management now wants to build Y fast. But wait, what about X? Nevermind, just build Y now. Okay, we're building Y, and X collapses... because it wasn't built to scale. Now we're being called in at 2 am to fix X while also expected to ship Y tomorrow. Sure, they'll glow you up and tell everyone what a hero you were for coming to the rescue at 2 am, but on that six month performance review, the blowup is used as reason to withhold raises and promotions. They don't lose any sleep of course, just you, the developer.
