I think for sure there are virtues to it. For a certain kind of mind (which maybe any mind can be trained for) being able to mainline 100 different ideas in the course of a couple of hours can give you truly amazing synthetic scope -- you can find connections between disparate things, develop an understanding of X as it relates to Y, and connect them to your existing scaffold. It's a very different feeling and outcome than drilling deep gets you.

It's a great mode to be in. But it's not the only mode you want to be in. At least, I certainly don't.
