Choosing a language before you even have an app matters. Changing the language your app is already written in or tacking on a microservice so you can use a 2nd language.... not such a good idea. I chose php 8 years ago because I already knew it. Would I write my app in a different language today if I could? Probably. Should I do that now, when I have very few bugs (basically none of which are related to my language choice) and no performance issues? Probably not. Have I been tempted because shiny? Yes. Delivering actual value to customers is what matters and there hasn't been anything I couldn't solve with a bit more PHP. Rewriting the whole app would probably kill my business.
