For serverless (as in AWS-lambda-like) I agree. In that usecase WASM provides a better security barrier than containers, with faster cold-start time (which is really important for the scaling promise of these services).
For the stuff people run on their Kubernetes clusters I have more mixed expectations. Containers are more universal, but I can totally see a microservice architecture running as a lot of WASM runtimes with a handful of containers.

Particularly in the case of Amazon lambdas, those are running in VMS already (firecracker). Why wouldn't you skip the VM and use a static binary from rust instead?
