AI is extraordinary. It can write, reason, summarise and decide - often better than we can. But there's a cost nobody's talking about: the less we exercise our own reasoning, the worse we get at it.

54% of American adults now read below a sixth-grade level. Reading scores are at their lowest since 1992. Numeracy scores have fallen in parallel - and only 48% of Americans can answer basic personal finance questions correctly. Critical thinking - the ability to assess an argument, spot a flaw, weigh evidence - is declining alongside them.

This matters because AI cannot replace the human judgement needed in the moments that actually count. Leaders who cannot reason independently, citizens who cannot evaluate an argument, professionals who outsource their thinking entirely - these are the real costs of cognitive atrophy.

The deeper risk is not that AI outthinks us. It's that we stop thinking altogether. Every major human discovery - from penicillin to the internet - came from a mind trained to question, connect and reason under uncertainty. If we outsource that capacity entirely, we don't just become dependent. We become passengers.
