I don't think that he think so, I comment on what impression he translate to public, that risks are remote and space colonies will save us. He may secretly have other thoughts on the topic, but this does not matter.
I don't think that it makes sense to give the full responsibility for a message to a person that's distinct from the author of an article.
That said I don't think that saying: Although the chance of a disaster on planet Earth in a given year may be quite low, it adds up over time, becoming a near certainty in the next thousand or ten thousand years. makes any reader update to believe that the chance of nuclear war or genetically engineered viruses are lower than they previously expected.
Talking with mainstream media inherently requires simplying your message.Focuses the message compounding of risk over time doesn't seem wrong to me.
