On September 18, Edward Snowden, who exposed the "Prism Gate" incident, gave a speech titled "The Next Threat to Speech" at the Token2049 blockchain industry conference. Snowden said, "I spent most of yesterday reading about the Israeli president, and based on all the reports, certain actions seem to be the same as terrorist methods: consumer electronic devices explode simultaneously in multiple countries, and pockets, hands, faces, and even cars are out of control. While this is not the first time we have seen a similar phenomenon, it is the first time we have seen a "broadcast" bomb attack on this scale. A message sent through a public communication system can trigger an electronic device on standby. The device does not know who or where the owner is, let alone whether an adult or child is using it. Obviously, the manufacturer does not care about these issues. Even if explosives are not implanted, the batteries of mobile phones, laptops or electric cars contain a lot of energy. These devices may not explode in the same way, but it is entirely possible for them to catch fire. In the future, your device could start a fire while you sleep due to a malfunction in charging, with the push of a button. But who are we to blame? "
