Given current IQ trends, humanity is getting dumber. Letās not mince words. This implies the AGI singularityāour long-heralded techno-apotheosisāwill arrive against a backdrop of cognitive decay. A dimming species, squinting into the algorithmic sun.
Now, Iād argue that AIāas instantiated in generative models like Claude and ChatGPTāalready outperforms at least half of the human population. Likely more. The only question worth asking is this: at what percentile does AI need to outperform the human herd to qualify as having āsurpassedā us?
Living in the United States, Iām painfully aware that the average IQ hovers somewhere in the mid-90sācomfortably below the global benchmark of 100. If youāre a cynic (and I sincerely hope you are), this explains quite a bit. The declining quality of discourse. The triumph of vibes over facts. The national obsession with astrology apps and conspiracy podcasts.
Harvard astronomer Avi Loeb argues that as humans outsource cognition to AI, they lose the capacity to think. It’s the old worry: if the machines do the heavy lifting, we grow intellectually flaccid. There are two prevailing metaphors. One, Platonic in origin, likens cognition to muscleāatrophying through neglect. Plato himself worried that writing would ruin memory. He wasnāt wrong.
But thereās a counterpoint: the cooking hypothesis. Once humans learned to heat food, digestion became easier, freeing up metabolic energy to grow bigger brains. In this light, AI might not be a crutch but a catalystāoffloading grunt work to make space for higher-order thought.
So which is it? Are we becoming intellectually enfeebled? Or are we on the cusp of a renaissanceāprovided we donāt burn it all down first?
Crucially, most people donāt use their full cognitive capacity anyway. So for the bottom halfāhell, maybe the bottom 70%ānothing is really lost. No oneās delegating their calculus homework to ChatGPT if they were never going to attempt it themselves. For the top 5%, AI is already a glorified research assistantāa handy tool, not a replacement.
The real question is what happens to the middle band. The workaday professionals. The strivers. The accountants, engineers, copywriters, and analysts hovering between the 70th and 95th percentilesāassuming our crude IQ heuristics even hold. They’re the ones who have just enough brainpower to be displaced.
Thatās where the cognitive carnage will be felt. Not in the depths, not at the heightsābut in the middle.
