For what it’s worth, I think both sides of this debate appear strangely overconfident in claims that seem quite nontrivial to me. When even properly interpreting the Landauer bound is challenging due to a lack of good understanding of the foundations of thermodynamics, it seems like you should be keeping a more open mind before seeing experimental results.
At this point, I think the remarkable agreement between the wire energies calculated by Jacob and the actual wire energies reported in the literature is too good to be a coincidence. However, I suspect the agreement might be the result of some dimensional analysis magic as opposed to his model actually being good. I’ve been suspicious of the de Broglie wavelength-sized tile model of a wire since the moment I first saw it, but it’s possible that there’s some other fundamental length scale that just so happens to be around 1 nm and therefore makes the formulas work out.
People have been sending binary information over wires since 1840, right? I don’t buy that there are important formulas related to electrical noise that are not captured by the textbook formulas. It’s an extremely mature field.
The Landauer limit was first proposed in 1961, so the fact that people have been sending binary information over wires since 1840 seems to be irrelevant in this context.
