> width is hedge - you don't get paid as much, but you can land a job quickly, because you can plug into any team
I generally like your model, but mobility is upstream of salary too. If you're very intentional about your career, mobility is the ace up your sleeve, letting you slot into the places you need to to maximize your current and future salary.
I've always been a pretty width-first engineer; it just fits my personality. But time and again, I've been able to open doors for myself because my established excellence in one area provided an "insurance policy" for teams to take a chance on me working in another (in-demand, specialized) area. After the first iteration or two, it's been a virtuous cycle, where I make lots of money with my established skill in the currently-hot thing and trade off a small portion of that to grow the skill in the next-to-be-hot thing.
Though perhaps this doesn't generalize well. I've been studying/working in AI for well over a decade and it's been a remarkable boom for my chosen field. Perhaps during the next AI winter, I'll have to face the depth/width trade-off a little more directly. But even in that case, it seems like width maximizes my expected salary.
You're absolutely correct. Great insight that mobility also increases salary!
Can I rubber duck you with another question? As someone who is also trying to maximize mobility and width, how do you feel about the idea of "it's not who you know vs what you know, it's who knows what you know"? In other words, when you move teams/jobs, how to you gain credibility? Do you do anything to promote/show your 'track record'?
