Yes, I believe that he was trying to say something along those lines. But that doesn't change the fact that it's a crass generalization to say something about a "PhD in Computer Science", as if they all shared the same brain.

If you ask me, PhD holders have demonstrated themselves far more capable of dealing with scut-work than your average human. Every PhD I know earned their degree only through years of drudgery and perseverance through vast stretches of boredom. They tend to laugh bitterly at those people who suggest that they're impractical dreamers, incapable of doing "real" work.

For my part, the only impractical dreaming I got done in graduate school were the bits where I imagined that I could make money with my skills when I graduated. :-P
