World’s total CPU Power: Roughly One Human Brain via @arstechnica

Lest we get too enamored with our technological prowess, however, the authors make some comparisons with biology. “To put our findings in perspective, the 6.4*1018 instructions per second that human kind can carry out on its general-purpose computers in 2007 are in the same ballpark area as the maximum number of nerve impulses executed by one human brain per second,” they write.

Our total storage capacity is the same as an adult human’s DNA. And there are several billion humans on the planet.

Just stumbled on a fantastic year-old article comparing the computational and storage power of society’s various forms of digital and analog computer systems over time.

It’s a bit dense, but some interesting highlights are the fact that gaming systems have always out-processed supercomputers, fixed internet connections have essentially replaced all other forms of connectivity, and ‘a 6cm^2 newspaper image is worth 1,000 words.’ Cute.

I’d love to see a cleverly designed infographic of this dataset!
