      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?

      in principle you could if you were patient enough; in practice, people start from near zero, and don't get that far In most domains of engineering we choose NOT to start with random search, w good reason Why should ML be different? Why ignore hints from products of evolution?

      Because we have a long tradition of getting it wrong when we hand implement them. Because it doesn't have to be random - we can learn across generation, eg epigenetic. Because we can be more efficient than nature. And because simulating billions of lives lived isn't out of reach.

      you are overcorrecting on the prior history, the same way people who dismissed DL in 2009 were....

          also simulating even *one* human brain is currently out of reach. possibly for a long time.

          “No, I'm not interested in developing a powerful brain. All I'm after is just a mediocre brain, something like the President of the American Telephone and Telegraph Company.” — Alan Turing I’ll leave it to the reader to offer a contemporary instance of the subject brain.

          I don't mean to imply that having no innate prior is the only way or even the best way. I am just arguing that it's not a completely crazy idea. CNNs are a good example of priors and they served us well.

          They have and they haven't. My view is that we have pushed them pretty hard and they still have *exactly* the same problems I pointed out seven years ago, when #deeplearning first became popular [ https://www.newyorker.com/news/news-desk/is-deep-learning-a-revolution-in-artificial-intelligence …]:pic.twitter.com/SZAvaWu199
