“Yet no nanocomputer or other complex circuit was built for a decade and a half. [32]  We had the devices. What we do not have, still, is simply the infrastructure that macroscopic technology takes for granted: the ability to sort and test parts; to cut and join materials; to create frameworks that can hold devices in designed relationships, and the ability to place parts into such frameworks.”

J Storrs Hall. “Where Is My Flying Car?: A Memoir of Future Past.”

I think I'm getting the hang of the Kan extension concept. For example, the future, at least in technology, seems to be a left Kan extension, while the past and the present would be the right one. This is just an initial idea I and sill need to develop a proof with specific examples, using the system model.

In the meantime, I"m hoping to finish the first draft of the book by the end of this year. It looks quite doable because I'm already halfway through the Cinderella part, which should be next to last.

the yellow fever will discourage the growth of great cities in our nation; & I view great cities as pestilential to the morals, the health and the liberties of man. true, they nourish some of the elegant arts; but the useful ones can thrive elsewhere, and less perfection in the others with more health virtue & freedom would be my choice.

As usual, the future looks crazy, the past [even when represented by major figures of that time] looks stupid.
