Arguments like "but AI cannot reliably multiply numbers" fundamentally misunderstand how AI works. AI cannot do basic math not because AI is stupid, but because basic math is an inherently difficult task for otherwise smart AI. Lots of human adults can do complex abstract thinking but when you ask them to count it's "one... two... three... five... wait I got lost".

> fundamentally misunderstand how AI works

Who does fundamentally understand how LLMs work? Many claims flying around these days, all backed by some of the largest investments ever collectively made by humans. Lots of money to be lost because of fundamental misunderstandings.

Personally, I find that AI influencers conveniently brush away any evidence (like inability to perform basic arithmetic) about how LLMs fundamentally work as something that should be ignored in favor of results like TFA.

Do LLMs have utility? Undoubtedly. But it’s a giant red flag for me that their fundamental limitations, of which there are many, are verboten to be spoken about.

You're not doing yourself a favor when you point out "but they can't do arithmetic!" as if anyone says otherwise. Yes, we all know they can't do arithmetic, and that's just how they work.

I feel like I'm saying "this hammer is so cool, it's made driving nails a breeze" and people go "but it can't screw screws in! Why won't anyone talk about that! Hammers really aren't all they're cracked up to be".

Maybe because society has invested $trillions into this hammer and influencers are trying to convince CEOs to fire everyone and buy a bunch of hammers instead.

My comment even said “LLMs have utility”. I gave an inch, and now the mile must be taken.

Saying that the fundamental limitations are things like counting the number of rs in strawberry is boring, though. That's how tokens work and it's trivial to work around.

Talking about how they find it hard to say they aren't sure of something is a much more interesting limitation to talk about, for example.

Sure, thank you for steelmanning my argument. I didn’t think I needed to actually spell out all of the fundamental limitations of LLMs in this specific thread. They are spoken at length across the web, but are often met with pushback, which was my entire point.

Here’s another one: LLMs do not have a memory property. Shut off the power and turn it back on and you lose all context. Any “memory” feature implemented by companies that sell LLM wrappers are a hack on top of how LLMs work, like seeding a context window before letting the user interact with the LLM.

		But that's also like saying "humans don't have a memory property, any 'memory' is in the hippocampus". It's not useful to say that "an LLM you don't bother to keep training has no memory". Of course it doesn't, you removed its ability to form new memories!

Because know one owns a $300 billion dollar hammer that literally runs on fancy calculators.
