It compiles python to we assembly which then runs on their modified V8 runtime. We assembly is generally a non solution to any problem, especially not this one.

It compiles python to we assembly which then runs on their modified V8 runtime. We assembly is generally a non solution to any problem, especially not this one. While it is convenient it is a clear lack of engineering ability that they can't implement a proper Python runtime. The reasons to not use wasm are many - the tool chains for emscripten are not well documented, hacky, and we're not built to the quality you'd expect from a compiler. After all it's doing something nothing was designed for. The performance will never be an improvement over a native engine, much of the context is lost in translation when compiling to wasm.
