This is one that a lot of people have trouble with. One of the best engineers I ever worked with was in his 60s at the time, and seems to have stopped learning new organizational systems sometime in the 1980s. Agile development processes were just newfangled bullshit to him.
He was hot shit at anything that required fine attention to detail, and implemented a distributed task system after I gave him a verbal thumbnail sketch. Correctly. The first time.
But I could see that his refusal to learn new things was interfering with his career all the same.
