For me the biggest issue is all the articles and videos showing how people run entire companies in WASM and then sample code with fn(i32, i32) i32. The interoperability between languages and pre-defined APIs like WASI are just not there yet and its just rough to use.

Of course crazy things can be (were already!) done with WASM, but it's more like Rust in the beginning and is still advertised as Go ;)
