Not your brain but rather a tiny little chip inside your brain, still would be a rather difficult task (that’s an understatement) to unbrick or replace it though. Unless they put a debug Port accessible from the outside you would need surgery if you needed to JTAG to unbrick it (probably would need it anyway since if they go this route they probably won’t let you access the pins you need to from the outside).
Imagine how high stakes it is to avoid bricking your brain.
