I've looked at Jeff Hawkin's On Intelligence. I don't see how it bears similarities Hofstadter's work. Notably, Jeff Hawkins is highly focused on brain anatomy while Hofstadster's work mostly starts at the level of logic and abstraction. Anyway, Hofstadter's (and his student Cabrera's) aim actually hasn't been to deliver a convincing industrial scale system but produce models that illuminate our understanding of thought. I'm not actually sure if that is the right way of doing it but it's worth noting they're not trying to "deliver" on the terms akin to today's neural networks.
