The Internet is a great thing, without a doubt. However, when we have an operating system in someones brain, you should be incredibly careful. IoT devices get hacked all the time, it could be deadly if the human brain could get hacked remotely by anyone in the world.
This is crucial to the survival of mankind. Not everything needs to be connected to the Internet. The moment the human brain can be hijacked by a government, we will go so far into 1984 that we will never come out, and it is highly likely to lead to the end of humanity.
