Pain is limited on both ends: on the input by damage to the physical
circuitry and on the response by the possible range of response.
Responses in the brain are limited by several mechanisms, such as
exhaustion of neurotransmitter stores at synapses, negative feedback
mechanisms such as downregulation of receptors, and, I suppose, the
total numbers of neurons that can be stimulated. That would not be a
problem in a simulation, if you were not concerned with modelling the
behaviour of a real brain. Just as you could build a structure 100km
tall as easily as one 100m tall by altering a few parameters in an
engineering program, so it should be possible to create unimaginable
pain or pleasure in a conscious AI program by changing a few parameters.
I don't think so. It's one thing to identify functional equivalents as 'pain'
and 'pleasure'; it's something else to claim they have the same scaling. I
can't think of anyway to establish an invariant scaling that would apply
equally to biological, evolve creatures and to robots.
