I believe the opposite. There's some kind of weird mentality in beginner/wannabe programmers (and HR, but that's unrelated) that when you pick language X then you're an X programmer for life.
Experienced people know that if you need a new language or library, you pick up a new language or library. Once you've learned a few, most of them aren't going to be very different and programming is programming. Of course it will look like work and maybe "experienced" people will be more work averse and less enthusiastic than "inexperienced" (meaning younger) people.

That heavily depends, if you tap into a green field project, yes. Or free reign over a complete rewrite of existing projects. But these things are more the exception than the regular case.
Even on green field project, ecosystem and available talents per framework will be a consideration most of the time.
There are also other things like being parent and wanting to take care of them that can come into consideration later in life. So more like more responsibilities constraints perspectives and choices than power corrupts in purely egoistic fashion.
