If a tweet takes 30 seconds to conceive, type, and submit, Elon Musk has spent 45 hours of his life tweeting -- no way to estimate how much time spent reading, which is usually a higher proportion for non-egomaniacs. Judging by the way he talks, he could have used that time a little more productively by reading a couple books. Conveniently, also much harder to tank your stock price while doing.
