Maybe I'm missing something, but this sounds like a silly argument for ternary. A ternary system seems like it would be decidedly harder to build a computer on top of. Control flow, bit masking, and a mountain of other useful things are all predicated on boolean logic. At best it would be a waste of an extra bit (or trit), and would also introduce ambiguity and complexity at the lowest levels of the machine, where simplicity is paramount.
But again, maybe I'm missing something. I'd be super interested to read about those soviet-era ternary systems the author mentioned.
