Working in software development, company pays Copilot due Microsoft tied, I use ChatGPT when doing stuff for myself. Somewhat limited for me still, I ask it to build me a programming kata similar to, say, Gilded Rose and it just creates the same kata. When I ask it to increment its difficulty it actually makes it simpler.
For source code Copilot is far better because it has the whole program as the context. ChatGPT got some pretty big oversights that new programmers might not even notice. For example, the other day I had to change every varchar / string field in a database from 255 to 1024 bytes programmatically, asked it to build me a C# program and it did so. But didn't update the indexes, so I asked it to rewrite the program to do so as well, so it did. However, it indexed every single field that modified regardless it had indexes or not, so I had to correct it again. A new programmer might have ran the original code and messed up search, or might have caught that and then indexed every single field even if unnecessary.
