In the words of Kurzweil earlier this year, in the future, the "robot virus" will give us "a full virtual reality experience from within the nervous system itself." In other words, our brains will be able to connect to the "cloud system".
"This is similar to the fact that we have increased our storage capacity by tens of thousands of times by using existing cloud computing, people in the future can completely expand their brains thanks to the internet. "
And if so, we will be able to live in a virtual world - just in the movie "Matrix".
