@Orbit Newflavor, the one on the left is the closed timeline curve computer from the Xeelee sci fi series, it's a temporal devices that work using FTL data that travel back in time and answer questions before they're asked. It breaks down problems into pieces and recursively solve them with time travel without the temporal paradox allowing for acausality. It brute force their way through every potential calculation, then send the correct answer back in time once it's been found, it do not wear out because they send the answer back before they even need to run on energy supply.
The right is path to victory which is pretty self explanatory.
