If you need maximum requests per second for sufficiently high volumes of traffic - ie, Stripe/Twitter/FB/whatever stuff - then yeah Ruby/Python/etc doesn't cut it. If your needs get extreme enough (high frequency trading?) then Java doesn't cut it either. Most (I suspect > 99%) use cases don't fit these criteria. I know this is skewed a perception is skewed a little by the HN crowd, where many folks legitimately are trying to build the next Stripe or Twitter, but I think the world of modern software development is somewhat poisoned by this belief that we all need to follow FAANG-scale practices and architectures.
