Gen AI is magical, it makes stuff appear out of thin air!

And it's limited, everything it makes kinda looks the same

And it's forgetful, it doesn't remember what it just did

And it's dangerous! It can make things that never happened

Starting with theory might be the simplest way to explain, but it leaves out the hook. Why should they care?

Some of the takeaways feel over-reliant on implementation details that don’t capture intent. E.g. something like “the LLM is just trying to predict the next word” sort of has the explanatory power of “your computer works because it’s just using binary”—like yeah, sure, practically speaking yes—but that’s just the most efficient way to lay out their respective architectures and could conceivably be changed from under you.

I wonder if something like neural style transfer would work as a prelude. It helps me. Don’t know how you’d introduce it, but with NST you have two objectives—content loss and style loss—and can see pretty quickly visually how the model balances between the two and where it fails.

The bigger picture here is that people came up with a bunch of desirable properties they wanted to see and a way to automatically fulfill some of them some of the time by looking at lots of examples, and it’s why you get a text box that can write like Shakespeare but can’t tell you whether your grandma will be okay after she went to the hospital an hour ago.

What I'd add: the lesson about hallucinations should come early, not just in the RAG module. Kids (and adults) need to internalize "confident-sounding doesn't mean correct" before they get too comfortable. The gap between fluency and accuracy is the thing that trips everyone up.

Us millennials didn’t do so great with native access to the internet, zoomers got wrecked growing up with social media. . . It’s rough.

The simplest explanation I can give is we have a machine that you feed it some text from the internet, and you turn the crank. Most machines we've had previously would stop getting better at predicting the next word after a few thousand cranks. You can crank the crank on an LLM 10^20 times and it will still get smarter. It will get so smart so quickly that no human can fit in their mind all the complexity of what it's built inside of it except through indirect methods but we know that it's getting smarter through benchmarks and some reasonably simple proofs that it can simulate any electronic circuit. We only understand how it works by the smallest increment of its intelligence improvement and through induction understanding that that should lead to further improvements in its intelligence.
