If your problems are interesting and we get along well, I will happily work on whatever out-of-fashion tech stack you have that the web development intelligentsia sneer at. And we'll do great things!

I had a blast making Wordpress development not suck and it led me down a lot of interesting roads and brand new ideas.

These other potential hires who only believe in The One True Stack are silly.

You can still make your SV rockstar programmer salary writing code in Java. Don't they still use it at Google?

But better yet, we have embraced Cloud Native, so between containers and microservices it doesn't really matter what language we use.

We use Java, Python, Go, Ruby, C++ and our front end is React.

Individually, every language we use is both powerful and flawed. But together it builds a pretty amazing platform.

But I really resent this sort of mentality. It causes a lot of work trying to 'upgrade' your tech stack when you'd get more benefit from fixing your architecture, refactoring, building new features, fixing bugs etc. I'd rather work on improving software in meaningful ways and make the company more money.

You don't have to like Java, but it is fine to use and there are plenty of potential hires.

Sure, but isn't Java basically the biggest language in the world? And it can't "limit development velocity" more than C++.
