The answer to his question now sits on the hard drives of millions of consumer computers around the world. This guy must be some sort of anti-psychic.
I strongly suspect that no nearby shopping mall has done more business this afternoon the entire internet has this month, either. Kurzweil, this guy is not.
Of course, we'd have to ignore the business the shopping malls do over the internet. So maybe all in person transactions at all shopping malls vs. all consumer purchases over the web, for an equal period.
Then I remembered I was on HN and everything went better than expected.
