Asimov's Positronics...
Even though it was 'developed' with a positive particle, it was not protons, but anti-electrons. Maybe Asimov was too ahead of us, because handling anti-matter is still beyond being simple and requires a lot of energy as it has to be contained by magnetic fields (or any kind of fields Asimov didn't share)... I agree with the WE stand point... that's the only chance for this specie survival.
