I for some reason interpreted this as replacing nuclear reactors. I like it my way more.

While I agree that it should be a last resort, as even I would only feel save accepting it on my deathbed, the reason why is that I simply want nothing more than to be a full robot. Without any biology to feed, only machine!

I was thinking more like nanobot that slowly replace your brain cells till it fully replaces them after a few month. As to make it a ship of Theseus problem, and not black mirror.

I like to think that the brain will eventually be digitized without the star trek transporter problem.

That took me a second, sadly it would have been a second too long. : [
