Yeah, this was Scott who creates comics (I forget the full name). His claim is that it's easier to be in the top 80% of two things rather than the top 90% of one thing.
You mean better than 99% of the population in two things together, rather than better than 90% in one. As in it's easier to be a top 1% percent programmer-laywer because there are so few of them, than it is to be a 10% lawyer or a top 10% programmer.
yep...that's what scott adams stand is..
It's from Scott Adams, the creator of Dilbert. The term used is often "skill stack" or "talent stack".
