While comparing apples and oranges, they neglected to mention the speed of the "molecular switches." The fastest neurons fire at around 200Hz. Most fire at around 20Hz. Transistors are around 100,000,000 times faster.
Oh and circuits conduct signals at 0.5c while neurons are lucky to go at 0.000001c (300 meters/sec).
- Shorel 16y agoThis really puts the book 'True Names' in perspective. May be the mailman could be a fast thinker.
- phlux 16y agoTrue, but our brains absorb massive amounts of information and process it in parallel whereas it is much more serial for computers.
- AngryParsley 16y agoAll parallel tasks can be efficiently serialized on a fast CPU but not all serial tasks can be efficiently parallelized on many slow CPUs. From http://lesswrong.com/lw/k5/cached_thoughts/ http://lesswrong.com/lw/k5/cached_thoughts/ : Can you imagine having to program using 100Hz CPUs, no matter how many of them you had? You'd also need a hundred billion processors just to get anything done in realtime.
