Description

Wasmi works with Motor OS out of the box (with default features disabled). It should also be possible to port wasmtime.

And we can probably tune Motor OS and/or a wasm runtime so that wasm/wasi is more efficient here than on e.g. Linux. But the overall wasm ecosystem on the "backend" (wasi) still seems a bit underdeveloped. For example, a lot of interesting bits and pieces have been ported to wasm in the browser (a whole Linux VM, vim, python, ssh client, terminal emulator, etc.), but not much to wasi.

So the question is whether it is worth it spending some time now on making wasm/wasi work great on Motor OS, or wait until the ecosystem matures?

Contributor guide

Research direction
Investigate the current state of WASM/WASI runtime support on Motor OS. Explore wasmi and wasmtime compatibility, assess ecosystem maturity, and determine whether investing effort now is worthwhile or waiting is better.
