- tsimionescu 5y agoAs someone else was noting, this result is based on Landauer's limit, which is itself ultimately based on the second law of thermodynamics. If Maxwell's demon existed, the second law would be wrong, so Landauer's limit would be wrong, so there could be a way to erase information without increasing entropy. I'm also not sure why Maxwell's demon would require erasure.
- bb88 5y agoWikipedia summarizes this well. https://en.m.wikipedia.org/wiki/Maxwell%27s_demon https://en.m.wikipedia.org/wiki/Maxwell%27s_demon I think it's clear that by now the 2nd law always wins. Always.
