Quick-Glance Summary

• 
  I walk you through an MIT experiment where 54 EEG-capped volunteers wrote essays three ways: pure brainpower, classic search, and ChatGPT assistance.


• 
  Brain-only writers lit up the most neurons and produced the freshest prose; the ChatGPT crowd churned out near-identical essays, remembered little, and racked up what the researchers dub
  cognitive debt :
  the interest you pay later for outsourcing thought today.


• 
  A bonus “switch” round yanked AI away from the LLM devotees (cue face-plant) and finally let the brain-first team play with the toy (they coped fine), proving skills first, tools second.


• 
  I spiced the tale with calculator nostalgia, a Belgian med-exam cheating fiasco, and Professor Felienne’s forklift-in-the-gym metaphor to land one mantra: *scaffolds beat shortcuts*.


• 
  We peeked at tech “enshittification” once investors demand returns, whispered “open-source” as the escape hatch, and I dared you to try a two-day test—outline solo, draft with AI, revise solo, then check what you still remember.


• 
  Net takeaway: keep AI on a leash; let
  thinking drive, tools navigate
  .


• 
  If you think I’m full of digital hot air, record your own rebuttal and prove it.
