Ironically, given Ben's post today, I was just thinking about emotions and
AGI robots - because I was on a vid. conference this week with Robert
Wenzel, who, also inspired by David Hanson, has some kind of AGI project
that wants to give robots emotions.
Nah, way too sophisticated I said - you always have to look to evolution -
and you see that evolution only introduces emotions down the line. I didn't
immediately have a precise reason why, though I knew it had something to do
with the complexity of journeys/activities that a creature undertakes. The
more complex the creature, the more complex its journeys/activities.
The more precise reason I now realise is that emotions demand *great powers
of reflection* - projective reflection of what WILL happen.
Take simple basic emotions like fear (or pleasure).
Ideally, you want a robot that can be afraid - afraid of a predator, say,
or simply falling off a cliff edge.
When you see a predator, the predator isn't actually doing anything to you.
You're afraid that he WILL do something to you. Ditto, on the cliff edge,
you're not actually falling or incurring injury. You're afraid that you WILL
fall off it.
Emotions then involve the capacity to run *projective movies* of what will
happen - the predator attacking you, your falling off the cliff. In addition
they require a bicameral mind, because the movies have to be run most of the
time in an unconscious mind , while the conscious mind attends to the
immediate situation.
Many of you guys will think you can achieve this by just attaching a few
symbols to the brain, and linking some reflex reactions. No. You have to be
able both to learn and unlearn new emotions - and that can only happen by
storing and rerunning movies. Emotions are extremely sophisticated stuff.
First we need general robots that can, like paramoecia or simple organisms,
creatively plot and execute many - potentially infinite - different paths
and routes to goals, by contrast with present narrow AI robots that only
have a few avenues. True autonomous mobile robots. Emotions - and emotive
robots - will come much later.
