Every now and then I like to review my old writings so I can cringe at all the wrong things I wrote, and say "oops" for each of them. Here we go...

There was once a time when the average human couldn't expect to live much past age thirty. (Jul 2012)

That's probably wrong. IIRC, previous eras' low life expectancy was mostly due to high child mortality.

We have not yet mentioned two small but significant developments leading us to agree with Schmidhuber (2012) that "progress toward self-improving AIs is already substantially beyond what many futurists and philosophers are aware of." These two developments are Marcus Hutter's universal and provably optimal AIXI agent model... and Jurgen Schmidhuber's universal self-improving Godel machine models... (May 2012)

This sentence is defensible for certain definitions of "significant," but I think it was a mistake to include this sentence (and the following quotes from Hutter and Schmidhuber) in the paper. AIXI and Godel machines probably aren't particularly important pieces of progress to AGI worth calling out like that. I added those paragraphs to section 2.4. not long before the submission deadline, and regretted it a couple months later.

one statistical prediction rule developed in 1995 predicts the price of mature Bordeaux red wines at auction better than expert wine tasters do. (Jan 2011)

No, that's a misreading of the study.

On September 26, 1983, Soviet officer Stanislav Petrov saved the world. (Nov 2011)

Eh, not really.

in the U.S., the administering charity need not spend from the donor-advised fund as the donor wishes, though they often do. (Jul 2012)

Silly. Donor-advised funds basically always fund as the donor wishes.
