### I would be very impressed by a machine capable of substituting for
human general reasoning abilities. It could be set to work on improving its
reasoning abilities, and then, of course, substituting for humans in all
jobs is likely to be not far behind.

### Of course, it would be hubris to claim that I know how far we are from
a human-equivalent intelligence but I can make some reasonable guesses.
Based on the complexity of the neural structures involved in volition,
building this volitional module would be more difficult than building a
walking robot but not dramatically so. The limbic system works very closely
with the cortex but aside from that it is not orders of magnitude more
complex than the brainstem. By weight it is a few times larger than the
brainstem if you include the relevant cortical areas, and the
neurophysiology is not different from the rest of the brain, so duplicating
its function in software shouldn't be a 50-year stumbling block on the way
to AGI.
