Reads like an opinion piece. Technically weak on details and the comparisons leave a lot to be desired

> I believe lowering costs by 3x is a strong enough motivator that it alone will motivate companies to make the switch to Isolate-based providers.

depends on so much more than price... like do I want to introduce a new vendor for this isolate stuff?

> An Isolate-based system can’t run arbitrary compiled code. Process-level isolation allows your Lambda to spin up any binary it might need. In an Isolate universe you have to either write your code in Javascript (we use a lot of TypeScript), or a language which targets WebAssembly like Go or Rust.

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

Containers are still the defacto standard

wasm has its place, especially for contained workloads that can be wrapped in strict capability boundaries compile-time (think, file-encoding jobs that shouldn't access anything else but said files: https://news.ycombinator.com/item?id=29112713).

afa FaaS is concerned, wasmedge [0], atmo [1], tarmac [2], krustlet [3], blueboat [4] and numerous other projects are turning up the heat [5]!
