ChatGPT can be surprisingly good at some things, but can also produce good-looking nonsense. The problem is that spotting those cases requires a certain level of knowledge of the subject, which makes the use of it kind of pointless. I personally use it for subjects where my knowledge is significantly below average, such as learning new frameworks / languages (e.g. React). It often gets stuck with more complex questions (e.g. questions related to x86 Assembly) or obscure subjects. I rely more on its ability to reproduce information than its problem-solving ability. I think the next development is adding LSP integration to the AI assistants and other tools to check its output.

However, I think most people don't use it the way I just described. A lot of people seem to mistake its ability to write code for an ability to understand code. It also sometimes uses older functions deprecated for security reasons, especially when using C. So yes, I think it will increase the amount of insecure code.
