Nope, I dont think knowing only one programming language is enough. It may be okay if u do not seek for advancement in your programming skills both technical and conceptual. But to fully understand this domain, it just inevitably requires us to learn other programming languages. It is part of the job, and I think it's fun to experience the journey of always-learning new things that we didnt know before. But one thing for sure, programming is not for everyone. Some type of personalities might just be too stressful when being asked to do this kind of job constantly.
"Some type of personalities might just be too stressful when being asked to do this kind of job constantly." - Couldn't agree more, I've witnessed people suffering to the point of becoming depressed; I can assure you it's not a pretty sight.
Regarding learning new languages, you're absolutely right. To progress and further yourself you need to improve and learn. I've never worked at a place that required you to know one language, but then I think this debate comes into play: "Quality over Quantity?"
