I personally appreciate the great progress made both by the field of neuroscience as well as by Numenta. I would dare to say (as my subjective opinion) that progress does not come in a linear continual process but rather as a series of quantum jumps. Some big ones and a few smaller jumps in between.
With each jump, we narrow the search space of possibilities that lead to AGI but also increase the focus. Within the new focal points, we can better identify some missing pieces, but can never predict when and how these pieces will be discovered. We know what we know. We also know some of what we don’t know. But we don’t know if there is more to what we don’t know. (The eternal dilemma of basic research).
I would be very interested in a high-level roadmap of what we expect to find on the path to AGI. (The expected milestones on our path to AGI.). Many of these milestones lie in the past, behind us. Numenta has been instrumental in many. But what do we expect to find ahead of us, on this path?
Finally, I would like to add, that in my opinion, this roadmap should be defined in terms of given functional capabilities and not in terms of areas of application. (Often times, goals and milestones are described as areas of application. That is not scientific in my opinion). Capabilities at a neurological, computing or cognitive set of dimensions would make more sense.
