After AlphaGo, the skill of human Go players noticeably improved. I suspect we will see a similar pattern in math.
Another major problem, this time in additive combinatorics, has fallen, this time to humans rather than AI, but using methods related to the AI solution to the unit distance conjecture.

If you don’t have any bitcoin be sure to thank the journalists, financial advisors, and economists for keeping you away from the stuff. They were right, and they continue to be right!

This is funny. What if you invested in the S&P 500 every time CNBC had a "Markets in Turmoil" special? Well... your average return after one year would be 40%, with a 100% success rate.

This is Bank of America's CEO Brian Moynihan. He's one of the worst investors in history. And you're probably paying for his losses. Since his bank bought $500 billion (yes, billion) in mortgage bonds at the all-time high price for those assets in history in 2020, the value of those securities has fallen by more than $100 billion. That's one of the largest single investment losses in history. For perspective, the Enron bankruptcy led to losses about half this size. But the bank hasn't had to report these losses against its earnings, so no one's bonus pay has been cut. Sweet deal, isn't? Meanwhile, Moynihan isn't worried. He knows he can recoup these loses by using the $1 trillion the bank holds in U.S. consumer deposits. How? By paying ZERO interest to America's consumers while paying billions to foreign creditors (!) to get the liquidity he needs to avoid having to sell those bonds and report huge losses. This racket has earned him more than $100 million personally since 2020, when he approved the bond purchases. Now do the banking regulations make sense? Lever up. Flip a coin. If heads, Moynihan wins. If tails... Moynihan wins! No matter what happens, Americans have their savings stolen.

Here's the quiet part out loud. With 10-year yields at 4.08%, the losses on "Held to Maturity" securities at America's largest banks are going to have dramatically worse prices, leading to big losses that, thanks to ridiculous accounting rules, they are allowed to hide. So, who's hiding the most?

S19K pro running at 2500W during the primary duty cycle, then it down clocks to 2000W for the remainder of the cycle. This setup gets 22.15W/TH @ 2500W and 19.5W/TH efficiency @ 2000W. Worth every penny.

I just got my fiancé, who is a senior structural engineer, to throw the hardest engineering problems she could at o1-preview. It was able to solve all of them, each one in under 60 seconds. The world of work has completely changed and most people don’t realise yet.

Contrary to what many believe, 2020/2021 represented the *peak* of wokeism, not the genesis. The woke movement gained much of its momentum in 2015, with—you guessed it—the announcement of Donald Trump’s presidential campaign.
