Biological brains achieve their ends with relatively low speeds and energies. Even simplistic substitution with equivalent electronic components would be hundreds of times faster, and I'm sure we'll do better than that. I don't see the difficulty in the conjecture.
> I also doubt very much that cognitive labor is the constraint that limits human progress
That statement is impossible to discuss without defining "human progress", but if the work of the world's universities for the next 100 years was available in one year's time, at the very least someone with access to that information would have a significant competitive advantage. It seems clear that the next 100 years will include significant advances in automated fabrication, at which point physical labor also essentially becomes cognitive labor.

Knowledge is only rarely produced by people thinking about problems. It's produced by mundane trial and error experimentation. Experiments that take time. And money.

It'll be interesting to see what we can learn at the different levels of emulation. > It's produced by mundane trial and error experimentation. Fair point, although experiments in computer science and applied mathematics can usually be carried out without constructing physical apparatus. Also identifying and designing experiments to efficiently characterize a problem space is a large part of experimentation. And again, once automated fabrication improves, some automated experimentation in physics and chemistry becomes possible.
