Well, it's not that he is the dark lord but rather that he is so far ahead of the curve in the craft of mathematical modeling in physics (he won the Fields Medal) that he can easily solve a lot of actual mundane problems but he chooses not to. Incidentally this seems to be the legacy of String Theory after 50 years, a powerful tool for mathematical modeling in physics and not a direct road to the ToE.

So, when you come up to him as a fellow theoretical physicist and criticize his "platonic" stance his reply would be - if he is bothered at all to answer: "Ah, so the thing you are working on, did you try ... gives essentially an elegant mathematical solution to your theoretical problem that you were trying to solve for months."

Of course this is embedded in an institutional failing - namely funding throughout the 50 years.

But as Planck - who found himself reluctantly in the middle of a turning point - remarked on how insurmountable institutions and the persons associated with it can become: Science progresses funeral by funeral.

On this note: Ed Witten's dad a theoretical physicist himself, still lives at the ripe age of 102.

@downvoter: don't shoot the messenger ... i'm just telling you how it is \o/
