Or molecular computing. The Earth has about 10^37 bits of data encoded in DNA*. Evolution executes a parallel algorithm that runs at 10^33 operations per second**. This far exceeds the 10^25 bits of memory and 10^27 OPS needed to simulate all the human brains on Earth as neural networks***. *Human DNA has 6 x 10^9 base pairs (diploid count) at 2 bits each ~ 10^10 bits. The human body has ~ 10^14 cells = 10^24 bits. There are ~ 10^10 humans ~ 10^34 bits. Humans make up 0.1% of the biomass ~ 10^37 bits. **Cell replication ranges from 20 minutes in bacteria to ~ 1 year in human tissue. Assume 10^-4 replications per second on average ~ 10^33 OPS. The figure would be much higher if you include RNA and protein synthesis. ***Assume 10^15 synapses per brain at 1 bit each and 10 ms resolution times 10^10 humans. -- Matt Mahoney, [EMAIL PROTECTED] ------------------------------------------- agi Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: https://www.listbox.com/member/?member_id=8660244&id_secret=117534816-b15a34 Powered by Listbox: http://www.listbox.com
