> It is fundamentally true, though, because you "level up" those skills through concentrated effort, which requires focus and time, both of which are finite resources.
I dunno. My experience is that it's true for some fields, such as videogames/sports.
What I've found is that people who have true expertise in a field (excluding videogames/sports) are generally competent in a number of other fields. The characteristics required to become an expert oil painter or an expert in applied mathematics (for example) are focus, concentration and the ability to recognise new patterns as patterns, and then apply them!
IOW, someone who is an actual master in a certain field should easily become at least competent in other things that they try.
