Only sometimes is it paid, and indeed the rise of the unpaid internship "for experience" is something of a problem.
While you may be correct in general, this is the guy who wrote the parenthetical at the end of the article who (presumably) runs Khan Academy's internship program.
I don't think I've heard of any unpaid internships at any decent technology companies.
Ah; sorry, I was referring to Khan Academy specifically.
That's interesting, thanks. Khan academy has been on my crush list for a while, it's fun to consider taking a break from consulting work to apply for an internship...
