> Are you only doing one thing on your computer? No.
You seem to be implying that doing multiple things on a computer means that every single side channel will be masked by noise indistinguishable from random. This is obviously false. Cryptographically secure random data doesn't just appear out of nowhere.
I'm not even concerned with the credibility of this article; side channel attacks are old news and will continue to be a threat for a long time (I'm guessing we don't even understand physics well enough yet to eliminate them completely, so there will still be new breaks all the time for the near future). Luckily, everyone is still too busy trying to remove their remote code vulnerabilities to deal with real issues like side channel attacks.
