It gives a false sense of security to beginner programmers and doesn’t offer a more tailored solution that a more practiced programmer might create. This can lead to a reduction in code quality and can introduce bugs and security holes over time. If you don’t know the syntax of a language how do you know it didn’t offer you something dangerous? I have copilot at work and the only thing I actually accept its suggestions for now are writing log statements and populating argument lists. While those both still require review they are generally faster than me typing them out. Most of the rest of what it gives me is undesired: it’s either too verbose, too hard to read, or just does something else entirely.
