I think what he implied was that more reliable calculations would come from reversible gates, though they'd ultimately be slower. The speed being one of the main reasons they weren't used in processor design. One of the solutions for that problem was the parallel design that could compensate for the slowdown of individual calculations by the ability to run many at the same time, and of course the increased rate of transmission by performing the calculations right within the memory instead of the added latency of fetching and storing values every values and performing every calculation synchronously. So I think it's more that memristors would be a solution that allows the use of reversible gates making for more reliable processors. If anybody else has any better insight, fire away.
