"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."?
