I am not an expert in any of the fields involved here, but does anyone know why they make the assumption that this will exceed the capability of modern or future non-bio hardware? > “…in [the] future may eventually surpass the performance of existing, purely silicon-based hardware…” Software and silicon has the benefit you don’t have to keep it alive, disease free, and there isn’t actual matter you need to scrape off some copper contact should something die. and would you even get gains in training speed, for example? How often are brain cells rearranging synapses/communicating when that requires physical matter be moved around? (Ions move over synapses? I’m no brain scientician) Feels like the ephemeral nature of the current software and silicon set up is a pretty good local minimum. I don’t know if somehow adding more matter and nature goo to it moves anywhere closer to the next minimum. They just say it’s better like that’s self evident? Anyone know why?
