WASM itself is likely to be successful in some niches, the industry has a know-how for bytecode VM's and integration with LLVM will make it stick for a long while. My bet are computation kernels for web, and porting whole native apps to web browsers via emscripten.

WASI is probably doomed to fail, so far it was proven to be challenging to make "write once run everywhere" API, for example it's difficult to abstract over epoll vs IOCP vs io_uring without reinventing libuv, but making a standard out of libuv API will make adopting any platform changes too slow, because of losing control over the implementation of the API. Having a single standard implementation where the industry is collaborating might be a better way, similar to how .NET is an abstraction over platform API.
