Google security researchers have come to the conclusion that speculative execution attacks are here to stay without drastic changes to modern CPU architectures, such as removing speculative execution entirely.

    (You remember that scene in the Snowden movie where they put their phones in the microwave? Amateurs! The phone can tell when it's in a faraday cage and can still hear soundwaves, and record them, and store them until it's not in a faraday cage anymore, then transmit them. I honestly don't care if they want to monitor me (they may even have a good reason for doing it) but I draw the line when they start impacting my ability to do good work by glitching my system up. That's when I cut them off, or at least, raise the bar so they have to work a little harder.)

    Just wrap the phone in foil and put in the fridge or something. Then move into another room. Signal will be dead and it's unlikely to pick up your conversation unless it has year-2050-grade microphone arrays.
