Has anyone seen a good use of AI in the wild? Every example I see is honestly depressing, such as this.

If someone is using AI effectively, there's often no way to tell that they're using AI at all. Toupée fallacy etc.

Code? not much, other than small functions/classes/prototype libraries to get started, but I've often used it to figure out where code was that I was concerned with in huge project code bases and analyze where some of the edges of interfaces are without digging for a few hours. Copilot can give a decent summary of where to look in a couple of seconds instead of a half hour of marking what I think are important sections and jumping around/grepping

It is best used for yack shaving in my opinion. Anything other than that and I feel like I cannot trust its output.

Its Code Generators all the way down...
