When writing was invented, societies started depending on long form memorization less, which is a cognitive "decline". When calculators were invented, societies started depending on mental math less, which is a cognitive "decline".
I'm sure LLMs are doing the same thing. People aren't getting dumber, they are just outsourcing tasks more, so that their brains spend more time on the tasks that can't be outsourced.
Also, domesticated dogs show indications of lower intelligence and memory than wolves. They don't have to plan complex strategies to find and kill food, anymore.
But humans need jobs, and jobs need to capture value from society. So we do actually still have to stay sharp, whatever form "sharp" takes.
If you're an entrepreneur, your job is to please the customer and to squeeze your vendors and employees. You still take little to no part in directly taking care of yourself, except as a hobby. Unless you want to be congratulated for wiping your own ass or lifting a fork to your mouth.
People who maintain a high level of curiosity or a have drive to create things will most assuredly benefit from using AI to outsource work that doesn't support those drives. It has the potential to free up more time for creative endeavors or those that require more deep thinking. Few would argue the benefit there.
Unfortunately, anti-intellectualism is rampant, media literacy is in decline, and a lot of people are content to consume content and not think unless they absolutely have to. Dopamine is a helluva drug.
If LLMs reduce the cognitive effort at work, and the people go home to doom scroll on social media or veg out in front of their streaming media of choice, it seems that we're heading down the path of creating a society of mindless automatons. Idiocracy is cited so often today that I hate to do so myself, but it seems increasingly prescient.
Edit: I also don't think that AI will enable a greater work-life harmony. The pandemic showed that a large number of jobs could effectively be done remotely. However, after the pandemic, there was significant "Return to Office" movement that almost seemed like retribution for believing we could achieve a better balance. Corporations won't pass on the time savings to their employees and enable things like 4-day work weeks. They'll simply expect more productivity from the employees they have.
Wouldn't that be the expected result here? Less knowledge, more questions?
When I use LLMs, it’s less about patching holes in my memory and more about taking an idea a few steps further than I otherwise might. For me it’s expanding the surface area of inquiry, not shrinking it. If the study’s thesis were true in my case, I’d expect to be less curious, not more.
Now that said I also have a healthy dose of skepticism for all output but I find for the general case I can at least explore my thoughts further than what I may have done in the past.
I don't have a dog in this fight, but "asking more questions" could be evidence of cognitive decline if you're having to ask more questions than ever!
It's easy to twist evidence to fit biases, which is why I'd hold judgement to better evidence comes through.
If I’m constantly asking “what does this mean again?” that would signal decline. But if I’m asking “what if I combine this with X?” or “what are the tradeoffs of Y?” that feels like the opposite: more engagement, not less.
That’s why I’m skeptical of blanket claims from one study, the lived experience doesn’t map so cleanly.
But if I'm teaching a class, and one student keeps asking questions that they feel the material raised, I don't tend to think "brain damage". I think "engaged and interested student".
Personally, I find myself often asking AI about things I wouldn't have been bothered to find out about before.
For example I've always these funny little grates on the outside of houses near me and wondered what they are. Googling "little grates outside houses" doesn't help at all. Give AI a vagueish description and it instantly tells you they are old boot scapers.
Maybe there is a movie in the back of my head or a song. Typical search engine queries would never find it. I can give super vague references to a LLM and with search enabled get an answer that’s correct often enough.
