The first part sounds reasonable.

I hadn't thought of English as a creole, even though it combines features of multiple languages, because there's no evidence of a pidgin evolutionary state. But, like a creole, it does have a substantially more systematized grammar than either its Scandinavian substrate or its French superstrate, both of which, for example, inflect for gender. And it certainly shows evidence of rapid historical change, like many creoles, and some of that seems to have been driven by decreolization-like processes. So maybe English really is a creole.

The linguistic analogy starts to break down there, though. In some sense all programming languages are pidgins, and of course they are conlangs.
