And it’s unlikely to be so anytime soon.

A human brain contains 100 billion neurons and over 100 trillion synaptic connections. That’s a thousand, or more, connections per neuron. A human brain’s cortex alone contains approximately 20 billion neocortical neurons, with an average of 7,000 synaptic connections each (primary source). The cerebral cortex has about 0.15 quadrillion synapses—or about a trillion synapses per cubic centimeter of cortex. More, the brain uses all of 20 watts of power to function fully. That works out to a vanishingly tiny amount of wattage per synapse (that’s 0 decimal point 12 zeros and a 2 at the end).

Intel’s latest AI-supportive chip suite (as of April 2024, anyway) supports up to 1.15 billion neurons and 128 billion synapses distributed over 140,544 neuromorphic processing cores[.] That’s a bit over 110 “synapses” per “neuron.” The setup uses 2,600 watts at max function. That works out to 0 decimal point 7 zeros and a 2. Which is five orders of magnitude more power drain per “synapse” for the chip than for our brain.

Artificial Intelligence isn’t all that. It may well get there, but not tomorrow.
