The human brain has about 10E12 neurons, and each neuron makes about 1000 connections (synapses) with other neurons, in average, for a total number of 10E15 synapses. In artificial neural networks, a synapsis can be simulated using a floating point number, which requires 4 bytes of memory to be represented in a computer. As a consequence, to simulate 10E15 synapses a total amount of 4*10E15 bytes (4 millions of Gigabytes) is required. Let us say that to simulate the whole human brain we need 8 millions of Gigabytes, including the auxiliary variables for storing neuron outputs and other internal brain states.
During the last 20 years, the RAM capacity increased exponentially by a factor of 10 every 4 years.By interpolation, we can derive the following equation, which gives the RAM size (in bytes) as a function of the year:
bytes = 10 ^ [(year - 1966)/4].
For example, from the equation we can find that in 1990 a personal computer was typically equipped with 1 Mbytes of RAM. In 1998, a typical configuration had 100 Mbytes of RAM, and so on.
By inverting the relation above, we can predict the year in which a computer will be equipped with a given amount of memory (assuming the RAM will continue to grow at the same rate):
year = 1966 + 4 log10 (bytes).
Now, to know the year in which a computer will be equipped with 8 millions of Gbytes of RAM, we have just to substitute that number in the equation above and compute the result.
The answer is:
year = 2029
