Earlier quoted context omitted.

If only there were some kind of international system of standard units.

Olympic swimming pools for liquids, times around the the earth for length and number of double decker busses for height.

For smaller lengths and radiation bananas are also acceptable.

Checking the arithmetic in every paper published seems like an good use case for LLMs. Has someone built a better version than uploading a PDF to ChatGPT and asking it to check the arithmetic?

LLM's are why we're in this mess, they can't do math or count r's

An LLM usually has a powerful digital computer right in its disposal, and could use it as a tool to do precise calculations.

> If the "half a million tons" figure were accurate, a single 1 GW data center would consume 1.7% of the world's annual copper supply. If we built 30 GW of capacity—a reasonable projection for the AI build-out—that sector alone would theoretically absorb almost half of all the copper mined on Earth. Quickly doing such "back of an envelope" calculations, and calling out things that seem outlandish, could be a useful f…

I think this is exactly the thing that should be done by a person without AI, to check what AI is writing.

Using your brain is so vastly more energy efficient, we might just only need half of that 30 GW capacity if fewer people had these leftpad-style knee-jerk reactions.

Nah just spin up an agentic ai proofreading agent on the cloud.

That can be true while also seeing value in using an AI to sanity check human-generated claims.

Modern reasoning models are actually pretty good at arithmetic and almost certainly would have caught this error if asked. Source: we benchmark this sort of stuff at my company and for the past year or so frontier models with a modest reasoning budget typically succeed at arithmetic problems (except for multiplication/division problems with many decimal places, which this isn't).

Interesting, how have you found they have been performing at more complex things like calculus and analysis?

Don’t forget cheetahs for velocity and elephants for weight.

More accurate to say they can’t see r’s. They process language but not letters.
