I disagree with the argument that you can't have a high level of skill in multiple parts of the stack without sacrificing a personal life. But I do tend to believe you can't operate at that skill level for each discipline at the same time. This is based on my own personal experience of course, but in any given job I tend to be full-stack, but with a bias towards a certain area of the stack. My contribution to the other areas of the stack is in more of an advisory/consultant role. On the other hand, I know full-stack devs who are far better at context-switching than I am. Subjectively I don't think their output is at the same quality as mine, but there is definite value in what they're able to do.
