“I come up with thousands of trillions of bytes of information to characterize what’s in a brain, which is millions of times greater than what is in the genome.”

Factual Science and research methods

Kurzweil estimates the brain's information content at thousands of trillions of bytes, millions of times greater than the genome.

Resolved true The record shows it happened or was so.

Factual: Statements about the present or the past, checked against the record: did they hold up?

The second judge would not resolve this claim; the verdict shown is the first judge's.

The evidence is the person's or their organisation's own records.

What would count as true or false

This is a claim about Kurzweil's own estimate, judged as of December 2002. True if his published writings or talks from around that time give an estimate of the brain's information content in the range of thousands of trillions of bytes (about 10^15–10^18) and describe it as millions of times greater than the genome. On standard figures the genome holds about 750 MB, or 30–100 MB compressed, so a ratio in the millions is consistent with those numbers. Mostly true if he gave the estimate but the figure or ratio differs a little from the quote, for example a different order of magnitude in one of the two parts. Mixed if only one of the two elements (the brain estimate or the comparison with the genome) appears in his work. Mostly false if his stated estimate was materially different. False if he made no such estimate.

    “There are about 800 million bytes in the uncompressed genome.”

Reasoning

In an email dialogue with Eric Drexler and Robert Bradbury published on KurzweilAI.net on December 3, 2002 (E1, E2), Kurzweil gives a figure of 10^16 bytes, considerably more than a 10^9-byte figure the other party had mentioned. 10^16 bytes is in the 10^15–10^18 range the criteria set. In the same collection of his writings, Kurzweil says the brain's interconnection data alone is a million times greater than the information in the genome (E3), and he puts the uncompressed genome at about 800 million bytes (E4). Together these match both parts of the quoted estimate. All of this comes from Kurzweil's own published writings, which is the relevant record for a claim about his own estimate.
