As a professional, my reasoning for NOT using AI is as follows:

1. I don't want to lose the muscle memory of what I do. Sure AI might be able to do annoying things like test templates... But that's not a skill I want to forget or lose, as self written unit tests have actually helped me catch mistakes that "would have worked" in prod (i.e. Code functions, but has undesired outcomes). AI can't usually spot that.
2. As a person who digs deep in cyber security and monitors heavily the malicious realm, I'm paranoid of malicious or weak code being spit into my repos.
3. I'm a privacy nut, too. Most "good" AI solutions are anti privacy.
4. If anyone here has done a proper code review of AI generated code from coworkers, they should know it adds a ton of extra time because of errors, inconsistencies with repo practices, etc and actually wastes the time of the developer and reviewers.

Am I saying "NEVER AI?"? nah. But it's far from ready for me personally to even consider for programming purposes. I'm also well aware this isn't what many others think or feel; I don't scream at people for using it if it's what they feel helps them.
