I don't know how people cope with the boredom of such a limited career. It's like deciding as a child that you like strawberry sauce and then being forced to eat strawberry sauce for the rest of your life.
It's madness.
I mean, if you don't like programming there are other careers; but I've never heard of a successful senior dev that a) wanted to switch in to management or PM, and b) couldn't do so easily.
Apparently! But to be clear, the reason I don't see this is because very few senior devs opt to move in to management (even less in to PM, scrum master, etc), not because there are so many management jobs available. And the converse (a senior dev complaining, "I feel like the business keeps pushing me towards roles with more leadership/meetings and less coding") is very common IME.
