Excellent point. I'd have difficulty believing this guy too, if he hadn't predicted millimeter wave full-body scanners wouldn't work before anybody in the media knew they wouldn't, based on the fact he'd been building them.
He says the main problem with LASIK is that when you correct myopia with it, your presbyopia (inevitable hyperopia from being over 40) is going to be worse by the same degree that the operation made the myopia better, and you're going to be stuck with it for much longer. Glasses or contacts for myopia you can just take off when you reach that age, but LASIK for myopia will need to be countercorrected. He didn't object to LASIK for hyperopia.
On ChrisHallquist's post extolling the virtues of money, the top comment is Eliezer pointing out the lack of concrete examples. Can anyone think of any? This is not just hypothetical: if I think your suggestion is good, I will try it (and report back on how it went)
I care about health, improving personal skills (particularly: programming, writing, people skills), gaining respect (particularly at work), and entertainment (these days: primarily books and computer games). If you think I should care about something else, feel free to suggest it.
I am early-twenties programmer living in San Francisco. In the interest of getting advice useful to more than one person, I'll omit further personal details.

If your idea requires significant ongoing time commitment, that is a major negative.
