Redundancy is probably the best option. That’s how the Voyager is still working after one of the computers failed.

- atoav 3y agoRedundancy is a very good option, but the "right" level of modularization helps too. You probably don't want to make everything out of FPGAs, but if your individual modules can be flexibly rewired on the fly and they are granular enough in their functionality to build new things, that adds yet another level of redundancy, as you might be able to replace a broken thing with the right combination of working modules.
- WalterBright 3y agoRedundancy is the straightforward way, two of everything. That still means two failures can cripple the machine. I'm talking about going beyond that. I.e if you need A and B and have modules X, Y, and Z, then any one of XYZ can fail and you still have full functionality. I.e. you can have more redundancy with fewer modules.
