lol, the spoiled times we live in that you think this. The human body is capable of surviving on very little.

A thing with protein, fat and sugar would sustain you for incredible amounts of time. Many many months if not years.

Only if you also ate some random other stuff you found lying around. Doesn't even have to provide much in the way of energy, just enough 'dirt' to round out your diet with whatever other essentials you need.

Human bodies have evolved to survive for a long time on relatively little, yes. But not to evolve for a very long time on a single source of very 'clean' food like snickers bars. 'Clean' in the sense that chemically snickers has relatively well defined inputs, whereas hungry humans would eat just about anything, including insects and grass and bark or leather.

This isn’t true. There are countless cases of people surviving for months on nearly no food at all.

I’m not talking about what it takes to stay alive for long term periods. I was refuting the silly idea that you would die after a couple of days/weeks of snickers.

How much vitamin C is in a snickers bar? I think you'd get scurvy within a month or two if that's all you had.

How much vitamin A? Night blindness. Vitamin B? Neurological issues, confusion.

That's the thing with mono-diets, your body needs a diverse range of things that it can't synthesise itself.

But to the core point, in cases where the output of an LLM is good enough, many already have much lower energy requirements than humans: o4-mini is currently priced at $1.1 per million tokens of input and $4.4/million tokens of output; if that's all being spent on electricity at $0.1/kWh, that's a max of 11 kWh/million tokens in and 44 kWh/million tokens out — how many calories would a human have to burn to read, write, hear, speak, and internally monologue the equivalent of a million tokens?
