Tilden's stuff models the way real neural circuits work, rather than trying to come up with a priori rules that approximate the outcome of a nueral network. One interesting thing about neural nets is that they learn, without needing a seperate memory apart from the nuerons that generate the movement. If you've even seen a Tilden 'bot fired up for the first time you'll see it learn to walk *without* the need for an external validation that says "yes, you're walking, now keep doing that". The same elements that generate the movement learn the pattern from feedabck from the environment. Now, no one's made a "nervous net" that mimics human linguistic behavior in the way that a lot of well-known top down AI programs do. But I would argue that Tilden's 'bots teach us far more about how the brain actually works than any top-down GOFAI program ever did.
