Blacknad: Don't ever listen to Uncle Al.
Yes, it is unbelievably possible for us to live in a Matrix type environment. Of course these machines wouldn't be like we use today simply
because the technology for as small as we;ve
gotten the hardware isn't fast enough. A 'cluster' of quantum computers could easily do the job
however once that level of technology is reached.
Along with the mysteriousness of quantum communication, who's to say it won't be possible to one day remotely exploit that functionality
for mind control? That would be a Matrix as well.
