Most of the posts mentioning Rust not being the best choicce for a startup talk about iteration speed and prototyping. In that light I don't think this is the best heuristic. If you need to prototype quickly and search for a market fit, then by all means, choose whatever will make you go fastest (and I'd argue for a lot of use cases it would be Elixir with Phoenix's LiveView if you don't absolutely need an SPA or a mobile app), but if you're building sth that already has a market, Rust might be still a good choice even if it's not a C/C++ fit.
