Pattern Matching vs. True Understanding: Models like ChatGPT predict the next likely word in a sequence based on weights and probabilities. They do not actually know or comprehend the meaning of the words they generate.
No Common Sense or Causal Reasoning: AI struggles with basic cause-and-effect logic that humans use effortlessly. It cannot reliably apply abstract logic or adapt its knowledge to completely unfamiliar real-world scenarios.
Narrow Focus: Every system today—from image generators to self-driving cars—is trained for one specific job. They cannot spontaneously think, feel, or shift skills to a brand-new domain the way a human mind can.
Lack of Consciousness: Strong AI requires self-awareness, emotions, and subjective experiences. Current machines are complex software programs running on hardware, with no inner life or agency.
Brute-Force Efficiency Gap: The human brain runs on about 20 watts of energy. Modern AI requires massive data centers consuming megawatts of power, showing that current systems use statistical brute force rather than true cognitive architecture.

No World Models: Modern AI predicts words or recognizes patterns, but it does not actually understand or model the physical world.
Missing Sensorimotor Learning: Humans learn by moving, touching, and interacting with our environment. Hawkins stresses that true intelligence requires this sensory-motor loop, which today’s AI lacks.
Energy Inefficiency: Deep learning activates all artificial neurons at once, making it power-hungry. The brain uses sparse representations (activating only about 2% of neurons at a time), making it radically more efficient.
