If you're worried about a meteor hitting SF (and I know that's a metaphor, but let me run with it), then your risk profile indicates you won't be using new technology from a new startup (you probably won't even use less risky stuff, like Rust or Elm).
If every technology had exactly the same constraints, then we'd be stuck with those constraints forever. This isn't the _right_ way to do it, it's just our vision of how to solve the problems with coding.
