AI is a 'cognitive hot dog' that weakens learning, argues Riley

AI is a 'cognitive hot dog' that weakens learning, argues Riley

3 Key Points

  1. What happened

    Benjamin Riley argues AI is a "cognitive hot dog" — appealing but harmful to cognitive development — and notes Norway banned AI in schools for students under 13, while OpenAI VP Leah Belsky said learners make up over half of ChatGPT's 900 million monthly users.

  2. Why it matters

    This suggests that treating AI as a learning tool may undermine the effortful thinking that builds durable knowledge, and that institutions like schools are starting to push back with bans.

  3. What to watch

    The real test is whether such bans spread and whether AI use in education shifts from occasional to routine, which Riley warns is where the harm lies. Watch for more school districts and countries following Norway's lead.

Context & Analysis

The essay traces the idea that brains are computers back to Alan Turing and notes that John von Neumann doubted the computational model could capture the "exceptional complexity of the human nervous system." Neuroscientist Paul Cisek offers an alternative: brains as feedback-control systems, not information processors. Riley uses this to argue that AI, like processed food, exploits ancient cravings but damages the systems we rely on.

The piece also highlights concrete examples of AI in education, such as OpenAI VP Leah Belsky's claim that learners are the majority of ChatGPT's 900 million monthly users, and Anthropic's "Claude for Teachers" initiative. Riley cites a recent study from China showing students stopped doing homework once they started using AI, harming their learning. He also points to pushback like Norway's ban and the Oberlin Luddite Club's open letter.

The stakes hinge on whether AI becomes a routine part of education or remains an occasional tool. If bans and resistance grow, it may signal a broader shift in how institutions view AI's role in learning. For educators and parents, the question is whether to prioritize convenience or protect the effortful thinking that builds durable knowledge.

FAQ
What is the "cognitive hot dog" argument?
Benjamin Riley argues AI is like junk food for the mind: appealing in the moment but undermining the cognitive systems humans evolved over millennia. He says the harm comes not from occasional use but from making AI part of our mental diet.
What did Norway do about AI in schools?
Norway recently banned essentially all uses of AI in school for students under the age of 13. In the US, a major teachers' union and school districts like Los Angeles and New York City have also implemented bans.
How many people use ChatGPT for learning?
OpenAI VP of education Leah Belsky said learners made up more than half of the 900 million average monthly users of ChatGPT, calling it the world's largest learning platform.
