I'm a polymath in mediocrity.

Unlimited blades > one blade

Mastering something is a LOT of work. I think variety is good and it makes a more fulfilling life, but it's definitely good that there are super experts out there that move humanity forward and stuff.

the thing about being knowledgeable about/skilled at multiple things is that in a lot of cases they compound or are a prerequisite for deeper understanding
it's why when studying biology you have to learn about chemistry and with historical events there's a bajillion different dimensions to dig into
building up an interrelated system of ideas greatly helps memorization as well
you also can't fix up your house by only being a master at hammering down nails, and as much as a single excellent element can serve to carry a piece of art it helps for it to be well rounded and not have any glaring issues
outside of their specific field, the master of one will more commonly fall in line with the lowest common denominator, whereas jack will be above average
this all can go a long ways

and then there's the pole-dancing archer with a zweihander over here talking about media and history while demonstrating stuff
