I have been thinking we would be heading for a world where WASM replaces code running lambda functions on the cloud for a long time. WASM is traditionally seen as running on a host platform, but there is no reason it needs to be this way. Because of the sandbox nature of WASM technically it could even run outside an operating system or in ring0 bypassing a lot of OS overhead. Compiling to WASM makes a whole range of deployment problems a lot simpler for the user and gives a lot of room for the hosting environment to do optimizations (maybe even custom hardware to make WASM run faster).
