MIT professor says AI is taking over your brain

My father encouraged me to avoid elevators and escalators to the extent possible. He worked in a high rise and used the stairs for the first 6 floors of the building. People would see him come out of the stair well on the sixth floor to catch the elevator the rest of the way. Some coworkers eventually picked up this habit. He's 87 and is one of the healthiest people I know.

It's not just elevators and LLMs, we should regularly question all our technology usage. I needed to solve a statistical problem recently and it is easy to brute force an approximation by running a few million iterations on a computer. But I forced myself to attempt a theoretical solution first. It only took a few minutes to rejuvenate concepts and "foundational cognitive ability" that would otherwise be fading.

Contrarian take: I don't feel this way at all.

I end up thinking _more_ about many subjects, analyzing them more deeply, using AI. Before search engines, if I wondered about subject X, it was unlikely I'd have a resource at hand that could really tell me about X. Maybe ask around, see if anyone in my circle had some knowledge or an opinion. But for most topics, there were no options. No one would know what that company makes, or why tungsten in light bulbs, or whatever. And for most questions, I was not going to go to the library or start a full research project. Just too effort-intensive. Post search engines, I could do a little research, if I was really interested. Maybe 50% or 60% of the time get a reasonable answer.

Now using AI I ask a lot more questions: Why tungsten? What is this "yarn works" thing on the map? What is my local high school's per-student budget, and how does that compare to the other school districts in the state? What is this thing? What's its history? Why this not that?

I'm curious and interested in a lot of the world around me. AI doesn't seem to be making me dumber; it seems to be enabling a much higher degree of curiosity and, better yet, a much higher degree of "finding out."

Your curiosity is enabled but is it being best served? You are being fed a single perspective on every question, a singular world view. You do not have the serendipitous exposure to a broad range of ideas and opinions we experience as we meander through information.

You Google about why tungsten is in light bulbs, you find yourself on a website about the history of lightbulbs written by a hobbyist that has spent decades thinking about lightbulbs. You click around, link after link, your world is expanded to include this lightbulb fanatic’s.

Personally, I find LLM answers to questions completely devoid of the substance that actually matters to my curious mind. Sure, when I’m working and need a concrete answer to a specific problem, an LLM can be a great help, but for personal curiosity, to expand my world, they suck.

To me, what you’re describing sounds like learning lots of trivia, not expanding your understanding of the world.

It increases signal to noise ratio in comparison to raw google results.

You might or might not miss that hobbyist web page. I can't say for certain, but I do know that most of my self learning explicitly includes going over the history of the topic.

Or you know, same scenario, but you are looking for information on how quanta work. You really can't make sense of the first 10 pages of google results, but you happen on "Motion Mountain" on the 11th page and you end up spending the next two years telling people the universe is made of little knots.

If that sounds like a pretty specific example, it's because it's a real one of someone I knew. I don't think the tool here is going to massively impact the quality. The person's judgement will play a way heavier role in that.

To each their own, I guess. If I find out that yarn works was a type of textile mill and spinning factory, I then read on about other parts of the textile industry in New England. Maybe how it relates to the progress of steam engines vs. hydro power, or its place in the Industrial Revolution overall. It gives me an on-ramp to understand one thing and branch out to others. I don't know what AI models or agents you're using, but they must be weak sauce. Mine give me sharp and specific answers, at least 2-5 references per question, and I can branch out to that lovingly curated blog, to Wikipedia, to local historical societies and their curated collections. Et cetera.

I end up reading more sources and exploring more things. If you want to dismiss that as "trivia," or dismiss the topics I want to know about, okay. But it's important to me. You could equally deride search engines as wanton seas of advertising, and tell me I need to head to a library and its paper-based card catalog, the only true and proper way to do research. :shrug:

It's true there are a lot of weak models out there. I tend to use the frontier models, and they are great research assistants IME.

I didn’t mean your topics of interest are trivial, I meant that LLMs reproduce information devoid of human perspective which turns it into just a bunch of trivia, facts without substance. A blog post about tungsten’s use in lightbulbs by a lightbulb fanatic is a fascinating insight into the subject built on their years of fanaticism, every word is meaningful. An LLM’s words mean nothing, it is bland, it is soulless, an LLM’s summarization of a blog post is not a more efficient way to consume the blog post, it is something altogether different.

That the answers of an LLM are “sharp” and “specific” is not a good thing. You are only experiencing the subject through your own lens, through your own questions, through your own sycophantic robot. The imperfect way that humans communicate is so important to broadening our horizons. Some of the most influential learnings I’ve experienced came from tangential lines in books and blogs. And when I’m reading, sitting, thinking, letting the words bounce around my head, I am forced to reconcile ideas myself, to consider, to think. Just saying “tell me more about x” or “why is x?” every time I have a thought leaves no room to really learn and grow.

Anyway, we are all different, if your curiosity can be satisfied by LLMs summarizing, great :)

Could you define what you mean by human perspective? If LLM models are trained on data that's generated by humans and the resultant weights represents a gestalt of that data, isn't the resulting output going to be token patterns that represent the human perspective? For code, I could get that argument so I suppose it depends on the data you're trying to get.

> Could you define what you mean by human perspective?

They can't. This is an "anti-consciousness" qualia argument adapted to a general purpose anti-ai argument.

They are arguing that meaning doesn't come from the accurate reproduction of information, but from the subjective, lived experience behind the words. That subjectivity can't be defined, it's the whole point. It will never be defined, no matter how far along we come.

For me, I don’t stop at the LLMs. I use them to do a deep semantic search of the internet. If all I want is a summary, then that may be as far as I go.

But frequently, I want more than just a summary, so the LLM is just a launching point for me to go do a deep dive on the sites it turns up.

Maybe you shouldn't take the "you" of this article personally, but as a reference to your 100 mouth breathing neighbors. Do you think the average person who spends their evening reposting troll memes and watching Tiktok videos is now using AI to enhance their understanding of the world?

To be fair we've already had decades of advancements that allow society to more than ever avoid expending any effort on actual thought, but I can only see AI continuing and expanding the trend, not reversing it.

> Maybe you shouldn't take the "you" of this article personally, but as a reference to your 100 mouth breathing neighbors.

That's great and all, but if policy is created for the lowest common denominator because of these 100 dopamine-depleted donkeys, is it going to impact me?

tbh I feel these headlines are kind of sensationalized, it's just about how you use AI, and that determines if it is beneficial for you or not

Anything like how the internet or search engines or telephone operators (lol) "change your brain" articles I guess could be written ("Why didn't you just manualy memorize or look up a phone number yourself, what, do you want to download a brainrot?!")

We're all becomming Dilberts manager. :|

When smart glasses get adopted and Ai is always 100% right ... do humans become know it alls with the answer to everything always seen in front of them? Also, how does that change the way we learn in terms of going to school for 13 to 14 years as we do now....

What terrifies me is the thought that knowing the answer everyone sees is wrong and everyone being incapable of thinking critically about it. Maybe this is a timeless problem, but I fear it getting worse.

It's got what plants crave!

Or it's controlled by Dr. Evil tho the initial phase of it that's completely and 100% correct so we get sucked in and then Dr. Evil in five or ten years starts manipulating humanity. Sounds not good ... to the point of even evil ;-)

Thats when the Tet arrives and lasers the moon to pieces :|

Are we living in the same reality because that’s already how it is.

Say what everyone who has an iphone or android phone is also wearing Meta Smart Display glasses? Those are only generation one smart display glasses, they have a lot of improving to do.

> Maybe this is a timeless problem, but I fear it getting worse.

It's both, I think. It seems to me that it happens during periods of fast technological advancement. We just happen to be living through a sustained period of that.

The historical precedent is that it slows down again after people get a chance to take in the new reality. I am not sure how comforting that is.

> knowing the answer everyone sees is wrong and everyone being incapable of thinking critically about it.

That's what already happens when people read newspapers.

Quite honestly, in my experience, the people I respect and call intelligent are not the ones that shy away from using new and interesting tools such as brain slugs.

AI is only one, of many, socialization vectors that shoots memes at you.

Many won't pay it any mind, but "AI" isms will slowly permeate through culture.

And AI psychosis is just the most vulnerables.
