Assuming his brain consumed the usual 20W, throughout his lifetime Einstein's grey matter would have gotten through about 4.6 billion Joules. Some napkin maths tells me ChatGPT consumes that much in about 2.8 milliseconds.

I don't think we're there yet.

The first number is off by an order of magnitude or two, and your napkin math estimate is higher than humanity's entire power production. Are you a human?

Last I checked, yes I am indeed human. Are you implying I'm a language model because you think my maths is wrong?

Ok let's see, 20 Watts is 20 joules per second. Einstein was alive for about 75 years, so that's 75x365x24x60x60 seconds by 20 Joules per second which is 47,304,000,000 Joules.

So you are correct, I dropped an order of magnitude.

Based on the numbers here: https://www.businessenergyuk.com/knowledge-hub/chatgpt-energ...

ChatGPT gets through 39.98 million kWh per day, or 1.4 x 10e14 Joules per day, about 1.6 x 10e9 Joules per second.

47,304,000,000 / 1,665,000,000 is about 28.4 seconds.

So you're right on two counts, I'm off by an order of magnitude and an erroneous milli prefix. Napkin maths huh.

I think the original point I was trying to make stands though.
