Submission + - The Titan Submersible Disaster Was Years in the Making, New Details Reveal (vanityfair.com)

AleRunner writes: In Vanity Fair Susan Casey writes about the engineering behind the Titan disaster:

"In a culture that has adopted the ridiculous mantra “move fast and break things,” that type of arrogance can get a person far. But in the deep ocean, the price of admission is humility—and it’s nonnegotiable. The abyss doesn’t care if you went to Princeton, or that your ancestors signed the Declaration of Independence. If you want to go down into her world, she sets the rules."

ChatGPT gets Maya dates wrong. I have asked it to convert Maya dates into Gregorian, and it always gets them wrong. When I tell it what the correct date is, it apologizes and tells me I am right.

John Linden and Victoria Bricker, the authors of the article being discussed, are well-respected scholars. So these are not the normal nut-jobs that talk about the Maya Calendar. I have yet to read more than the summary, but will read the article in the next few days. I am sure that Linden and Bricker got the math and astronomy right. However, I am very suspicious that this is how the Maya actually used the 819 day count. There are only about 21 of these 819 day counts recorded in the Maya inscriptions, so proving anything about these is very difficult. 819 is the multiplication of 7x9x13, three periods frequently used by the Maya, so it is more probable that it is just a larger period that comes from these three smaller periods.

I can't see how that's a stupid question. It seems very important for AI and transhumanism, and the answer is neither obvious nor well-established. Is there some reason the question should not be asked?

Do you believe it is possible (in principle, not practice) for a faithful simulation of a human brain to exist, and would it be self aware?
