I agree. BUT - the response will be: “well even if we wanted to, we don’t have the technology to read his brain. we DO have the technology to read his phone, but you nerds are keeping it from us.”
(Disclaimer: I don’t agree with this position but I have a lot of friends who think the government can do no wrong)
And if we had the technology to read the brain we would demand to read everyones brain 24/7
It's not a perfect analogy. The problem with the "back door" is that these keys will leak. They always do. It's a big danger to have a weakness in all our devices that we know, eventually, Russia, China, or Iran will get their hands on.
