Why GPT-3 Can’t Understand Anything

Without long-term memory, human conversation becomes impossible

There is a mathematical reason why machine learning systems like GPT-3 are incapable of understanding. The reason comes down to the fact that machine learning has no memory. It is just probabilistic associations. If there is only a 10% chance of going off topic, then after just seven exchanges there is a greater than 50% chance the machine learning model has gone off topic. The problem is that when prediction is just based on probabilities, the likelihood of making a misprediction increases exponentially. A long-term memory is needed in order to maintain long-term coherence. GPT-3 is essentially a sophisticated Markov process. What is important about the Markov process is that the next step in the process is only dependent on…
