I don't need an AI to write my code, since I can write code myself. That said, it could be nice to have an AI inspect my code and point out anything it suspects might be a bug... there are already lots of static analysis tools that do this sort of thing and they are great, but I think AI might be able to find different classes of bug that are beyond the capabilities of static analysis.
Going a bit further, what would be even more useful is an AI that can run my program and exercise its GUI (or fuzz its inputs) and monitor the resulting behavior the way a human would, to look for faults during execution. Human-driven SQA is always a lot of tedious work, and a production bottleneck.
