@ESYudkowsky @gwern @postpostpostr @JeffDean I lack the general thermodynamic intuitions to judge that. But without an _irreversible computation_ happening in that step, the Landauer Limit has no need to apply AFAIU. FWIW I don't trust or understand @gwer
@anderssandberg @ESYudkowsky @gwern @postpostpostr @JeffDean Here's a couple citations: 1. https://t.co/GBdOor0tXW concludes the Landauer limit for one neural firing's worth of ATP is about 61GB. 2. To claim that limit is saturated, one needs to count no
A straightforward calculation shows that an action potential in a typical mammalian cortical pyramidal cell can process up to approximately 3.4 · 10^11 bits of thermodynamic information, or about 4.9 · 10^11 bits of Shannon entropy. https://t.co/SdSDlcgQsH
