At a fundamental level, brains don’t operate on floating point numbers encoded in bits.
They have chemicals to facilitate electrochemical reactions which can affect how they respond to input. They don’t throw away all knowledge of what they just said. They change continuously, not just in fixed training loops. They don’t operate in turns.
I could go on.
Honestly the number of people who just heard “learning,” “neural networks,” and “memory” and assume that AI must be acting like a biological brain is insane.
Truly a marvel of marketing.
