You don't have to convince me.

LLMs are neat, code generation is neat, but I do wish that people had learned type theory and instead used those.

I'm not aware of djinn, but I do remember the "Type Driven Development" that Idris had that I thought was absurdly cool; when you make the type specification clear enough, there ends up being basically exactly one reasonable way of writing the code, in which case it can just be "deduced" by machinery.

I'm a huge advocate for formal methods, and it does sort of bother me that pretty much all work on that seems to have been refocused on AI.
