I've long surfed the interwebs using Firefox with Adblock Plus, NoScript and DoNotTrackMe add-ons installed, and, along with regularly cleaning out unwanted cookies with CCleaner, I've almost never seen an unwanted ad and (knock on wood) never had malware installed my machine or the ones I maintain. Life goes on and it's good, mostly.
CEOs are not afraid of creating machines that will annihilate all humans. Their resemblance to humans is sufficiently remote that the machines will not regard them as a threat.
