This is just another reminder to not trust exchanges with your money and to not use them any more than necessary.
How will you buy and sell Bitcoins if there are no exchanges ??
I didn't say not to use them, as bolded, but to use them sparingly. Don't trust them with obscene amounts, etc., etc. Exchanges, even as they are now, are necessary for adoption and I don't want them to disappear. I want them to be better, but who knows if that'll happen.
But yeah, people who would rather not use them at all still have peer-to-peer alternatives available so it's not all bad.
