All for the low price of 125 watts, but you need to sleep one fourth of the time, during which it doesn't do much, and on the other three thirds "Most brains don't treat themselves to an abundance of training data".
I'm not sure I'd call this machine efficient at using its computational power.
- danielbarla 3y agoAlso, that is the net energy expenditure of the body, but not the input required. We use a relatively antiquated form of the internal combustion engine to turn food into energy, which seems to be around 25% efficient, at best. It's also built on chains of other fairly inefficient biological entities, so it's hard to say what the overall efficiency is, but suffice to say that we're prevented from using the most efficient energy sources.
- L_226 3y ago> during which it doesn't do much I know this was in jest, but if sleep was not a critical biological process we would have evolved to not do it already
- vasco 3y agoIt's basically a cleaning cycle for the brain. If we don't sleep we die pretty soon. Meaning it's necessary daily scheduled maintenance downtime, which should count directly to efficiency calculations!
