- It's scary that it does so well. It certainly manages to explain much better than the error messages of most compilers/static analysis tools.
- It's scary that people are going to trust this. Because it is, of course, an approximation. It can misunderstand. And if you're not at least as good as the tool, you won't be able to realize that it has misunderstood.
- I expect that, by now, there is already production code relying on such tools. I would consider this a form of cutting corners. It can save you time, but you have to be really, really, really sure of which corners you are cutting. And if you use such tools, by definition, it's because you delegate the knowing to a tool that won't tell you which corners you are cutting. Which I find dangerous.
- And of course, as with all AI tools, I'm sure it's going to be used one of these days to demonstrate something laughably false in a court of law.
