I tried it with a small test program (provided by one of the f77 codes). It took more time to fix the mistakes than if I would have done it myself. This is already one year ago. So likely things have improved a lot. I think the biggest issue for me are the small bugs that are difficult to detect. Yes, humans make those too. But if you wrote it yourself, it is easier to debug. That became very clear in my test. I am affraid that we are all becoming reviewers for these AI beasts. Review is the most boring part of the SW development process.
