I don't know about you, but I don't think too many people would like that part about "missing parts of the skull" being replaced by "dental cement". The operation sounds like it would be very involved, very high-risk. Therefore, the need for someone to be wired up to this type of technology must be enormously great in order to justify the risk. It's definitely not a toy or something to play around with. Only people who absolutely "need" this would go for it.

Now, we must define "need". People have gotten along without this for centuries. How much of a "need" is this?
