Definitely not. Maybe there's a lot of competition for full stack jobs, but at least in Vancouver, that's increasingly where more of the demand is.

Most companies have let people go, stopped hiring, or reduced the rate at which their headcount increases. Whether it's a good idea or not, that puts more companies in the spot of needing 1 engineer to do the work of 2, and the simplest way people see to do that is hiring full stack developers.

Even full stack aside, it makes hiring easier if I can keep hiring JavaScript engineers instead of needing some JavaScript, some Java. Companies all around the world need web apps and apps built, and will for a long time to come, and more and more of them are moving to a majority-Js(/TS) stack.

It's not like COBOL where you have systems which need maintenance and a retiring generation of engineers. There are still an abundance of java or C# or sql devs out there.

Do what you love, and if that's c#, go for it. But if I had no preference, I would go deep on JavaScript.
