Grady Booch says the AI-brain analogy is vague, unsupported, and overblown

Grady Booch doubles down on his criticism, saying the paper’s observation is vague and unsupported, yet is being inflated into a claim that AI and brains were “formed the same way.”

He argues that calling LLMs “evolved” also misses the point: humans drive their development, unlike the blind evolutionary process behind the human mind. He closes by comparing the argument to claiming soap bubbles and organic cells are convergently evolved simply because both involve surface tension.
