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.</div><div><br></div><div>Rafał</div></div></div>
