Much like self-driving cars being better than drunk, incompetent, or texting human drivers, AI software is generally better than the garbage churned out by code monkeys who don't care or cheap lowest bidder outsourcers.

It's nowhere near the quality of hand-crafted expert human code, but that requires a hand-crafting expert human engineer and takes a long time.

I predict that the latter will be reserved for the highest value, longest lived, or special (high performance, high security) parts of systems.
