That's why you're good. 🤷‍♀️

You're not the sort of programmer he's worried about having a look at his code, tho, as you're just curious and learning new techniques or how to implement some NIP.

You still go build your own thing, often in a different language, which is too much effort for a copy-cat.

I mean, we used to reverse-engineer implementations from compiled code, and you can soon probably have AI do that for you. 

 yeah, at some point soon hiding code will be a waste of time and cheap to reverse 

 And this is why I think closed-source is a dead end.  It's too easy to figure out implementations, if you're motivated enough.
