Fair to say obsolete, as computation, not serial communication, which isn't really computation, though some logic gates ("computation") to implement, needed, just not like a CPU/ALU is done that way. |

While 1-bit computing is obsolete, 1-bit [[serial communication]] is still used in modern computers, that are otherwise e.g. 64-bit, and thus also have much larger buses.
While 1-bit CPUs are obsolete, the first (research) [[carbon nanotube computer]] from 2013 is a 1-bit [[one-instruction set computer]] (and has only 178 transistors; since it has only one instruction<!-- SUBNEG (subtract and branch if negative) --> though it can emulate 20 [[MIPS architecture|MIPS]] instructions).<ref name="Courtland_2013"/>
