A priori probability estimates are always silly. That being said, I think the idea is that he is providing an a priori probability estimate for our reality actually being virtual and (to put it in terms of The Matrix) most 'human beings' being Agents.

it's not the fact that he was providing a probability estimate what gave me a chuckle, it's the fact that the author of the article felt the need to remind us that it was ONLY an estimate. :-)

and (to put it in terms of The Matrix) most 'human beings' being Agents.

Actually, you got it flipped around, in the Matrix, "most" human beings aren't Agents, they're Coppertops. The remaining few either live in "Zion" or fly around in Morpheus's hovercraft. Yeah, ok, now it all makes sense ;-)
