From the 100W consumed by the brain most of it is to keep the autonomic functions (respiratory, cardiac, digestion, processing senses [eyesight, hearing, touch, etc.]), actual thinking, executive function, language processing, etc. is a small percentage of the 100W in use.
- ben_w 3y agoYes, 20 watts or so for just the brain. But those 30 watts on the laptop also cover the screen, hard drive, wifi, etc. If you want to count the brain alone, then it must be compared with just the silicon alone; if you want to count the whole body, then it must be compared with the whole machine.
- postalrat 3y agoSounds fair if the laptop is capable of most of what the body can do an vice versa. Maybe fair when we have bipedal robots doing work for us.
- ben_w 3y agoDepends what you want with the thing. If the question is "I want to get this much mental stuff done", then you need the brain and the cost of keeping the brain alive and connected to the outside world — which for a human brain is the body, and for a silicon "brain" the computer/network. If you want a humanoid robot to do be a drop-in replacement for human labourers in all professions, then sure (modulo the open question of how much brain power all our jobs actually require) a whole robot body has to be ready and you need to compare that body to our body. If you want a special purpose machine that fully automates one specific product line but doesn't need to move, the "brain" might just be punched cards: https://en.wikipedia.org/wiki/Jacquard_machine https://en.wikipedia.org/wiki/Jacquard_machine
