since I first heard about it, with the earliest warnings I remember seeing coming from teachers.
Correction - the earliest I saw via social media came from teachers - very worried teachers, some becoming despairing - but IIRC the very earliest acknowledgment of what AI use can do to the brain that I read about was an article about a self-published author using AI to help her churn out books. She'd quickly discovered that the more she used AI, the less her own brain was involved in what she was writing, so the fewer ideas it gave her, and the more dependent she became on AI. So she'd try to back off AI use a bit, but she loved how fast it wrote so much that she couldn't give it up. Already addicted.
And I remember seeing social media messages about ChatGPT being down for a while, just a few months after its release in late 2022, and people admitting they felt helpless at work - felt they couldn't even finish stuff they'd started. Stuff they'd been able to do without ChatGPT before.
Since using our brains is important for avoiding dementia, I'm wondering if AI use might even lead to much more dementia, and maybe at earlier ages, in the future.
That's a really scary thought.
So is a future with more and more adults who aren't at all educated - who faked their way through school - and who are dependent on AI tools controlled by oligarchs who don't care at all about most of society and will happily assist autocrats and help them maintain power.
