In it and it's author's defense: http://news.bbc.co.uk/2/hi/health/5167938.stm This is a recent break through that would imply that half of the challenge (capturing brain output with technology) is already overcome. I notice that this evidence pertains to the motor cortex, but given this would it be impossible to download people's thoughts and memories? I hear that memories are more elusive and I've never heard of where conscious thought takes place. Going one step further (that other half of the challenge) how difficult would it be to 'write' to the brain with technology? Would it be impossible to hijack sensory inputs to the brain with technology?
