This does not follow, except for stripping away the religious/spiritual part. Computers are amazing! So is hardware! And so is the dance of software and hardware that makes magic happen.
I've seen nothing so far in this whole thread that would convince me I should stop thinking about my body as the meatsack carrying my brain, as every argument I've read so far triggered my "religious/spiritual mumbo jumbo" detector quite hard.
This is not to say the body isn't an important and tightly integrated part of the experience. But the fact remains that a hand or a heart or a lung can be removed or replaced without loss of self. A brain can't.
