> I can't shake the feeling that I am not building anything novel and someone with basic software engineering background can replicate the idea with the help of AI.
Why are you so fussed about what tool is being used? The product should be novel, not whether it's AI or not.
As long as the product is good, why would customers care if it's AI or not? There have also been plenty of existing products calling themselves AI if that's all you're after.
The world is huge. Even without AI, there are enough people that can replicate most things these days. OpenAI thought it was "safe". No so eh?
