The problem, even with a spinal cord cut intentionally and carefully, is that the surgeon has no way to know what connections in the head go to what connections in the body.
It sounds like he's simply hoping it all sorts itself out somehow. Or maybe that the brain could eventually remap everything. Seems unlikely. Especially within two years.
The basic idea would be physiotherapy afterwards to make the brain re-learn how to move the body
There has been plenty of people here who have claimed that Linux and open source provide an architecture which is by design more resilient against malware than proprietary solutions.
It is. That is why a Linux malware get to be news whereas yet another Windows malware does not register above the noise as news because there are so damn many of them. The same thing with the Bash, GnuTLS, OpenSSL etc vulnerabilities. "More resilient" does not mean immune - claiming immiunity would just be silly. News of Critical Vulnerabilities in Windows are about as frequent as every Patch Tuesday.
With your bare hands?!?
