Wither polymaths?

So is [the demise of polymaths] a problem to worry about, or not? After all, specialization has resulted in marvelous things that no one in 1800 could have dreamed of. The one potential problem is that creativity so often comes by joining concepts from two or more different areas-so if everyone only knows one area, this creative combination might never happen.

(I’ve always loved that word, polymath.)
