      A language can say what its *values* are without becoming totemic. Easier to vet a feature for "safe" than "simple"

      imo "fast" is just an easier to grok/measure proxy for "provides control".

      Not necessarily though. Mathematica is fast. It does not provide control. Depends on the context.

      But for general purpose languages, yes, so far "fast" has been a proxy for "provides control".

      I don't love this. asm.js provides control, but that doesn't make *JS* fast.

      most dynamic languages have a lot of control (FFI, C APIs) but the lang itself isn't "fast"

      but tl;dr: you want safe, control, ergonomic. Good control implies a more continuous tradeoff space.

      a good example is Rust having a great parallel story by adding a bit of cost to the sequential story.

          the fact that the parallel story is "free" makes the whole thing smooth and continuous 2/2

          I don't need concurrency to justify ownership. Ownership makes single-thread collections fast as hell.

          You also need a small fraction of Rust's borrowck complexity for data race safety.

          If you are willing to lose scoped threading, you just need the notion of 'static vs non-'static.

          some of the edgy tradeoffs (not the basics of ownership) end up being about concurrency.
