If a one-nanosecond process constituted "nanotechnology", then the first
1GHz transistor would have been "nanotech". To convert seconds to meters,
multiply by the speed of light; 3 x 10^8 m/s. One nanosecond, then,
equals 300 millimeters - hardly verging on the nanoscale! Actual
nanotechnology would involve... why, attoseconds, in fact. Or at least
femtoseconds - I'm pretty sure I saw those being tossed around in
_Nanosystems_.

If I recall correctly, a nucleon (proton or neutron) is around the order
of a femtometer; femtotechnology, then, would involve timescales on the
order of yoctoseconds. Attotechnology would be... well, the metric
prefixes don't go that high, so we might as well call it nano-attoseconds.

Would even muononium or monopolium work for attometer-scale precision?
I'd think that only chromotechnology would count as "attotech".
