from a tech article I read today, on the exponential growth in computer power

• We achieve one Human Brain capability (2 * 10^16 cps) for $1,000 around the year 2023.
• We achieve one Human Brain capability (2 * 10^16 cps) for one cent around the year 2037.
• We achieve one Human Race capability (2 * 10^26 cps) for $1,000 around the year 2049.
• We achieve one Human Race capability (2 * 10^26 cps) for one cent around the year 2059.

So in 50 years, it's possible that the brain capacity of the entire human race will cost us 1 cent, and one small cellphone will be almost infinitely more powerful than all of humanity.
