> With modern CPU's having so many cores and threads being so cheap, couldn't NASA use these for redundancy? Bold No. CMOS technology have one drawback - it is prone to latch up by ionization, because it have The parasitic p-n-p-n thyristor (it is locked in wrong state, to reset must do full power off). Rad-hardened designs have to deal with this, they used special type of die material and clamping diodes, so their technology essentially different from civilian designs.
