It's fine you have that opinion. I disagree and so do many others. I've used ai to generate notes, checklists, letters,.emails, work templates etc.
The output was correct and valid in most cases. What about the foundation is rotten, in your view? The fact that it's based on other people's work being regurgitated, or the environmental concerns, or how big tech is trying to leverage it to be an arbiter of knowledge and computing power? All are valid concerns, but they don't mean the technology is inherently unusable or unethical.
Banning it because of the views of some is unfair on the views of others. I do think that marking it is appropriate, so that anyone who objects to its use can avoid it. I would be concerned that over time or becomes impossible to avoid though. However, that's the point of open source. People can fork projects at the point where there is no AI code (except in the case where that is purposefully obfuscated).
