On December 25th, former Coinbase Chief Technology Officer Balaji published an article saying that in the future, smart cars, smart watches and smart homes will be widely used. Each object can not only communicate with people, but also communicate with each other, record conversations and coordinate tasks for its owner who holds the private key. He called this trend "AIoT". In response, Vitalik Buterin responded that ensuring that the ownership of the device belongs to the private key holder is not a default result, and requires human efforts to achieve it.
