WebAssembly is a binary format that your compiler writes to. It's not something you would ever write by hand or those people do. All the browsers are supporting and all that stuff. Did it really originate with Mozilla? Or was it?) Yeah, I felt like Rust and WebAssembly and all that Stuff kind of came from you guys. Exactly. And another Mozilla person gave a pretty interesting call to action around WebAssembly last year and one of the PyCon keynotes at the US PyCon. Were you there for that? I wasn't there. But actually, what's interesting about that is I had already been working on PyDide for a few months when he gave that talk.
