But if we are going to accept the computational inefficiency, what do we gain for it? If our only answer, collectively, as developers, is the richness of the ecosystem, then perhaps we should be moving our time and energies to make a rich ecosystem in either a language/runtime environment that performs better (C/Rust/OCaml/Whatever) or one that encourages correctness and/or speed of development. I know some people think javascript is the latter, and I can't prove them wrong, but I suspect that is not true.
