I'm not saying that you _cannot_ do it. But tell me: why has no programming-language done that? They all could have chosen to serialize their code or AST into json but they didn't. (except JsonLogic I guess)
Or do you think we are at our peak?
You mean like every single idea/project/etc that ever existed before their invention?
From now on, when someone tells me something is a bad idea, I'll take it mean that I should examine it further.
