"The half-life of a public corporation today is about 30 years: ten half-lives out — 300 years hence — we may expect only one in a million to survive."

Am I the only one who read this and went "Wait, 10 half-lives... that's 1/(2^10)... that would mean about 1 in 1,000 survive -- not 1 in 1,000,000."?

Ah -- didn't see that. Wasn't so much a criticism (it doesn't take away from the article at all) as it was an observation that something really trivial stuck in my head ;)
