ChatGPT is useful but is not a good model for human-like reasoning, since it needs a large training data set and consumes lots of energy. A thread on how far we are away from brain-inspired autonomous agents that, like humans, go out in the world and learn purposeful behavior. The 1st step is to accept Bayesian (probabilistic) reasoning as the gold standard for reliable information processing. Yet, the adoption of Bayesian reasoning proceeds slowly in many relevant engineering fields such as signal processing and machine learning.
