Why humans will never understand AI - BBC Future

It may have looked like clunky blocks of circuitry, soldered together by hand in a mass of wires and boxes, but what Cowan was witnessing was an early analogue form of a neural network – a precursor to the most advanced artificial intelligence of today, including the much discussed ChatGPT with its ability to generate written content in response to almost any command. ChatGPT's underlying technology is a neural network. As Cowan and Taylor stood and watched the machine work, they had no idea exactly how it was managing to perform this task. The answer to Taylor's mystery machine brain can be found somewhere in its "analogue neurons", in the associations made by its machine memory and, most importantly, in the fact that its automated functioning couldn't really be fully explained. It would take decades for these systems to find their purpose and for that power to be unlocked.
