You see this everywhere, but it's usually only with people who do not have much experience. Not just with languages either. I remember my team looking incredulously at a new hire who was, (hopefully anyway?), trying to show us all how smart he was by telling us Bellman-Ford was better than Dijkstra. Um. OK. But who cares? Our job is to ship product. We'll throw it at the GPU and move on with our lives. Thanks though? I think? If I was looking at a company that purported to be making an online game streaming service and they were using Ruby or Swift, I'd very likely look elsewhere for employment. If they were using Java, Rust, or C++, well, that would make more sense. There are just some realities out there about which languages to use for what, and if a company you are looking at seems to be operating way outside those realities? I mean you have to think long and hard about working with them. Same with employees by the way. If someone comes in and tries to get my teams to work on a Rust based inferencing service to host our models because "It won't take more than 6 months." Again, you have to question that person's judgement. We're supposed to spend 6 months, (read 18 months because it always takes 3x what they say), creating a Rust based service? A service that even my junior AI guys can push out by the end of the week in Python or Java? No thanks. HR, please prepare his/her separation notice. I don't run a "who has the biggest balls/breasts" contest. I run a tech firm. Fanboyism has no place in cold dispassionate decision making.
