Although I thought this was a good talk and I liked the fellow presenting it to me it seems fairly clear that little or no progress has been made in this area over the last decade or so. In the early 1990s I wrote somewhat similar simulations where agents had their own neural networks whose

Yes, resulted behaviors are not impressive, I did similar thing with essentially 1 hidden layer perceptron on 2D square grid in high school and got something that looked not much simpler (weak creatures cycling around gathering, fat carnivores in the center hunting them, few superfat parasites

I think that linguistic interaction with human beings is going to be what lifts Second Life proto-AGI's beyond the glass ceiling... Our first SL agents won't have language generation or language learning capability, but I think that introducing it is really essential, esp. given the limitations

Which raises the question of whether the same complexity glass ceiling will be encountered when running AGI controlled agents within Second Life. SL is probably more complex than polyworld, although that could be debatable depending upon your definition of complexity. One factor which would

No worries!! just wanted to clarify... To address your question more usefully: There is soo much evidence that chemistry is subtly important for biology in ways that are poorly understood. In neuroscience for instance the chemistry of synaptic transmission btw neurons is still weakly
