If your project is something that's trivial and nobody just thought to do it before you and bothered to do it after, that's probably not going to survive, but if your project is a small focused tool that handles something difficult really well, it's 100% got a future.

I declined as I'm just that strongly opposed to my work being used to train AI models and further entrench the enshittification of the internet.
