      What is the least amount of innate machinery we would need to build an intelligent creature? My proposal from 2018 [https://arxiv.org/pdf/1801.05667.pdf …] is below.

      Isn't innate machinery an architecture search done through natural selection? Unless you believe in intelligent design, that machinery did emerge on its own through world interactions. Why not try to simulate this search process rather than hand designing the machinery?

      Taken this to its logical conclusion, we should simulate the laws of physics so that we can first discover the transistor.

      No. There is no "should" in my tweet but a "can". I am not saying it's the only approach. I am saying it's a valid approach.

      Replying to @an_open_mind @GaryMarcus and

      It is a valid approach. But my point still stands: you have decided on a starting point based on the privileged position of a computer scientist, which is already far down the chain of evolution. Why not let simulation discover mechanics other than neurons, for example?

      You and Gary are both, in effect, choosing different starting points, wouldn’t you agree?

      Sure. Both approaches can be argued for and we should not take a principled approach. Improving current AI systems may need more innate knowledge or may not. And the best way to demonstrate which approach is most promising is to build more robust and useful AI with it.

      right, but the current explorations have been massively weighted towards the blank slate end of the spectrum. maybe time for some balance?

          Indeed, if we’d gotten ahead of the evolutionary game as Arthur C Clarke projected, we’d already have our own HAL.pic.twitter.com/EJoxv17twb

          Arguably, the correct black-box approach will illuminate the other way. For example, a two-tier ML system can be used to first reduce data to "important but general basics" (generalise), then many specific ML structures can use the output to do, say, specific object recognition.

          -so, as long as there is an information bandwidth chokepoint at the output of the 1st tier, and as long as the training set includes ALL the specific objects, labeled and all, then the system cannot help but come up a generalization (in the 1st tier), that is "universally" useful
