Ken Purnell Says 86 Billion-Neuron Brain Still Outpaces AI in Adaptive Learning

Summary
CQUniversity's Ken Purnell told an international webinar that AI still cannot match the human brain's ability to adapt, learn from experience and make sense of changing environments.
About 86 billion neurons matter less than the brain's constantly rewired connections, he said, arguing that neuroplasticity lets people continually reshape knowledge and behavior across their lives.
Purnell said modern AI already borrows from neuroscience through neural networks, predictive processing and attention mechanisms, but machines still lack emotion, context, relationships and lived experience.
That gap also shows up in memory: humans reconstruct memories each time rather than replaying them, a flexibility he described as central to human intelligence and future brain-inspired computing.
Should AI copy the human brain's flaws, or become a new, unbiased form of intelligence?
As AI learns to think more like us, are we forgetting how to think for ourselves?
Can neuroscience unlock the brain's 20-watt efficiency for AI, or is it an impossible goal?
Human Brain vs. Artificial Intelligence: Measuring the Impact of AI on Cognitive Development in Schools (2025–2026)
Overview
This report explores how rapid advancements in artificial intelligence from 2025 to 2026 have led to a major rethinking of human intelligence. As machines become better at analysis, calculation, and pattern recognition, the unique strengths of the human brain—such as wisdom, emotional understanding, and adaptability—stand out even more. The report highlights that while society once valued humans for their analytical skills, AI’s rise now reveals the irreplaceable value of human qualities. It also discusses the brain’s biological complexity and adaptability, showing why human intelligence remains unmatched despite AI’s progress.
