Well. They did, at the time. 

We have records from centuries -- even millennia back -- of scholars at the time complaining that these new-fangled "books" were turning their students lazy; why, they can barely recite any poems in their entirety any more! And there are people still alive today who remember life before widely available calculators, and some of them complained -- then and now -- that bringing them into schools dealt a ruinous blow to math education, and now these young people don't even know how to use a slide-rule.

And the thing is:

They weren't wrong.

The human brain can, when called on, perform incredible feats of memorization. Bards and skalds of old could memorize and recite poems and epics that were thousands of lines long. This is a skill that is largely lost to most of the population. It's not needed any more, and so it is not practiced.

There is a definite generational gap, between the people who were trained on slide-rules and reckoning and the generation that was taught on calculators. There came a year, when that first generation grew up and entered the workforce, when you suddenly started encountering grown adults who could not do math -- not even the very basic arithmetic needed to count down from one hundred. I would go into a shop, buy an item for sixteen dollars, give the cashier a twenty and a one because I want a fiver back, and have them stare at the money in incomprehension -- what do? They don't know how to subtract sixteen from twenty-one. They don't know how to calculate a fifteen-percent tip. They did not exercise the parts of their brain that handle this, because they always had a calculator to do it for them.

Nowadays, newer point-of-sale machines compensate for this; they will automatically calculate and dispense the change, no subtraction necessary on the part of the operator. Nowadays everyone carries a phone, and every phone carries a calculator, so if you need to do these calculations, the tool is right there. As more and more transactions go electronic and card, and cash fades further and further out of daily life, these situations happen less and less; it's not a problem that most people can't do math (until it is.)

The people who complained that these tools-that-replace-thinking would reduce the ability of the broad population to exercise these cognitive skills weren't wrong. It's simply that, as the pace of life changed, the environment changed so that in day-to-day life these skills were largely unnecessary.

So.

Isn't this, ChatGPT and Generative AI, just the latest in a long series of tool-replaces-thought that has, broadly, worked out well for us? What's different about this?

Well, two things are different.

1) In the previous instances of tool-replaces-thinking, the cognitive skill that it replaced was a discrete and, on a day-to-day basis, unnecessary outlay of energy. Most people don't need to memorize thousands of lines of poetry, or anything else for that matter. Most people don't need to do more than cursory levels of math on a day to day basis. 

This, however, is different. The cognitive skill that is being obsoleted here is more than "how to write essay" or "identify what is the capital of Rhode Island." It encompasses the entire field of being able to generate new thoughts; of being able to consider and analyze new information; of being able to follow logical trains to their conclusions; of being able to order your thoughts to construct rational arguments; or indeed of being able to express yourself in any structured way. These cognitive tools are not occasional use; they are every day, all the time. 

2) In the previous instances of tool-replaces-thinking, the tool was good at what it did.

Calculators may have replaced reckoning, but calculators are also pretty good at what they do. The calculator will, as long as you give the right input, give the right answer. ChatGPT cannot be relied on to do this. ChatGPT will tell you, confidently and unhesitantly and dangerously, that 2+2=5, and it will not care that it is wrong.

Books may have replaced memorization, and books certainly could be wrong; but a fact, once in a book, is pretty stable and steady. There is not a risk that the Guy Who Owns All The Encylopedias might wake up one day and decide -- to pick a purely hypothetical example -- that the Gulf of Mexico is called something else, and suddenly all the encyclopedias say that.

Generative AI fails on both these counts. It fails on every count. It's inaccurate, it's unethical, it's unreliable, it's wrong.

I remember some time ago seeing someone say (it was a video about medieval footwear, actually) that "humans have a great energy-saving system: if we can be lazy about something, we are."

This is not a ethical judgment about humans; this is how life works. Animals -- including humans -- will not do something the hard way if they can do it the easy way; this basic principle of conservation of resources is universal and morally neutral. Cognition is biologically expensive, and though our environment is not what it once was, every person still goes through every day choosing what is valuable enough to expend resources on and what is not.

Because of this, I don't know if there is any solution, here. I think pushing back against the downhill flush of the-easy-way-out is a battle both uphill and against the tide.

So I'll just close with this warning, instead: 

I know Google has been a staple of your very, very young life, but I promise there are other search engines out there and you can use them. Like, even right now.

I haven’t had any issue with DDG “ignoring“ keywords, but after years of using Google, I did have to relearn how to use the Boolean search engine without Google’s assistance. That’s an early Internet era skill that some younger generations may not have expereience with, but as a skill can be learned.

She got the idea for the study while walking with her advisor at Stanford to discuss her thesis topic, and the paper she eventually published in the Journal of Experimental Psychology in 2014 is sharp enough that it should have ended the seated meeting on the day it came out.

She ran 4 experiments on 176 people. Same person tested twice. Once sitting, once walking. The creativity tasks were the standard ones psychologists have used for decades to measure how good a brain is at generating novel useful ideas.

81% of participants in the first experiment produced more creative ideas while walking than while sitting. In the second experiment, 88%. In the third, 100%. Every single person walked into a more creative version of themselves. On average, people generated 60% more novel useful ideas the moment their legs started moving.

The skeptical question is the obvious one. Maybe it was the fresh air. Maybe it was the scenery passing by. Maybe it was the change of environment doing the work, not the walking itself.

Oppezzo killed every one of those explanations with one experimental decision. She put people on a treadmill facing a blank wall. No scenery. No fresh air. No environmental change. Just legs moving in place while staring at white drywall. The 60% boost held.

Then she ran the experiment that closed the case completely. She took participants outside in two conditions. Half of them walked through a Stanford courtyard. The other half were pushed through the exact same courtyard in a wheelchair. Same outdoor stimulation. Same scenery passing at the same speed. The only difference was whether the legs were moving.

The walkers produced dramatically more novel high-quality ideas than the wheelchair group. The outdoors did almost nothing on its own. The walking did everything.

She also tested the opposite kind of thinking. Convergent thinking. The kind where there is one right answer and you have to narrow down to it. Word puzzles where 3 words share a hidden fourth word that connects them. The seated participants did slightly better on these. Walkers got slightly worse.

Walking is not a general intelligence enhancer. It does one specific thing. It opens up the divergent search inside your brain. The part that generates options. The part that produces unexpected connections. The part that takes a problem and finds five ways into it instead of one.

When you need to converge on the single right answer, sit down. When you need to find the answer in the first place, get up.

The mechanism is now well understood. Walking selectively activates what neuroscientists call the default mode network, the system inside your brain that runs when you are not consciously focused on anything. The DMN is where mind-wandering happens. Where memories cross-reference each other. Where ideas that have been sitting in separate folders inside your head finally bump into each other.

When you sit at a desk and force yourself to concentrate, you suppress the DMN. When you walk at a natural pace, the executive part of your brain gets just busy enough handling the walking that the DMN comes online and starts doing the work that focus was blocking.

The most useful finding in the entire paper is the one almost nobody quotes. The boost did not turn off the moment people stopped walking. Participants who walked first and then sat back down stayed elevated. Their next round of seated creativity work was still significantly better than people who had been sitting the whole time. The rest lingered for at least several minutes after the legs stopped moving.

You do not need to do creative work while walking. You need to walk before the creative work. The brain holds the state.
