> If one writes Go or Rust, there are much better ways to run them than targeting WASM

Is there a similar priced way to run Go or Rust with similarly fast cold starts and low latency?

I think this is the real selling point of isolates; inefficient if you want to run a postgres server but perfect for low latency edge stuff.

There is the usual argument that on premise/dedicated servers scales way better that people expect, nonetheless the trend seems to be a move towards smart CDNs...
