Check your math. 10^14 is 100 Teraflop.

Speed isn't the only aspect. There's also information
stored in the pattern of synapses and their states.
It's not just that a synapse exists, but where it
is located on the source neuron (affects timing),
and where it is located on the target neuron and
whether it is inhibitory or exitory.

So let us say that 10 bytes of info exist per synapse
x 10^4 synapses/neuron x 10^11 neurons = 10^16
bytes (10,000 Terabytes = 20,000 large hard drives)

Given that it takes ~20 years for a human to grow up,
you are feeding an average of 16 MB/s into storage.
I don't know what that translates to as raw sense data
before our eyes and ears process it, probably a lot

So if you want your AI to be ready for use in less
than 20 years, you would have to feed it faster and
have more processing capacity.
