Balaji envisions artificial intelligence and the Internet of Things, and Vitalik reminds that private key ownership requires hard work
Balaji, former CTO of Coinbase, tweeted that in the future, smart cars, smart watches and smart homes will be widely used, and each object will not only be able to 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 "AI Internet of Things". In response, Vitalik Buterin emphasized that ensuring that the ownership of the device belongs to the private key holder is not a default result, and it requires human efforts to promote it.
