Imagine your net worth is $200,000. One day an armed gang comes up to your house and demands $10,000. “Don’t worry!” the leader says. “I’m only going to do this one time. Plus, it’s only 5% of your net worth. What’s the big deal ?” After he leaves, you call the cops, but they aren’t interested in investigating the matter. “What’s the big deal?” they tell you. “After all, it’s only 5% of your net worth!” As you’re preparing to flee the city for a place where you cannot be robbed, Gabriel Zucman appears on your doorstep. “Why are you leaving?” he asks. “Somebody just robbed me and the police aren’t going to do anything. I want to live somewhere I can’t be robbed!” “But sir,” says Mr Zucman, “Have you considered the fact that the man told you it was a one-time tax ? Have you considered that you gain nothing by leaving since the tax is already paid ? There’s no economic reason for you to leave anymore.”

What amazes me is the attitude of so many of the centibillionaires. A 5% tax will not make any difference to the way they live. Their spending may be extravagant, but it is still much less than their (correctly measured) income. They know that, as gifted as some of them indeed are, they have benefited from extreme luck (and the help of the state, and, to speak like an economist, monopoly rents). They know that their effective tax rate is low, relative to what many others pay. They know that extreme inequality is extremely unpopular, and can lead to political unrest, backlash, or worse. They must admit that, morally, it is hard to argue for a society in which some become obscenely wealthy, while so many are poor and see their income stagnate. They typically have not indicated that they are building their wealth to eventually make the world a better place. But they are still willing to fight the tax, spending hundreds of millions in California to avoid paying the tax. Why? They simply think what is theirs is theirs, end of story. They believe in the slippery slope, and if they do not take a stand on this levy, the government will come back for more. They hate the state and the notion that their money will be misused? Or?

Replying to @RoKhanna
Ro, thanks for the Wisconsin history lesson. You skipped the ending. In 1911 Wisconsin's income tax started at 1% on income over $1,000, about $18,500 today. Most people paid nothing. It was sold as a tax on the few. Today Wisconsin taxes working families starting at 3.5% and tops out at 7.65%. Washington copied the idea in 1913, and fewer than 10% of Americans paid it as late as 1939. Now it's in every paycheck. That's the real lesson of 1911... a tax on "the few" is how you build the machine that taxes everyone. And California already did this before... Prop 30 in 2012 was a "temporary" tax on high earners. Prop 55 extended it to 2030. Temporary in Sacramento means forever. Now look at Prop 40... A 5% grab on net worth, which means paper wealth and private company stock valued by a state formula, not money anyone actually made. Written into the state Constitution, with a clause letting the Legislature amend it by a two-thirds vote if it "furthers the purposes" of the act. "One-time" money for permanent health programs. When it runs out, guess who they come for next. Even Gavin Newsom says it "makes no sense" and is "really damaging to the state." Larry Page, Sergey Brin and Peter Thiel didn't wait around to find out. The LAO warns the state loses income tax revenue every year after the ones who leave are gone. And his chart makes the case against you... 5% "takes them back 31 days." So this wrecks California's reputation for capital, chases out the people who pay a huge share of the income tax, and doesn't even dent the "inequality" you claim to care about. It's not innovative. It's the oldest socialist trick there is... promise it's only them, then come for you. Vote NO on 40.

"Math was made by humans for humans" And now humans have given math the ability to think about itself, and reach into the dark unknown, bringing back new knowledge. If you can't see how gloriously transcendent and divine this is, I feel bad for you.
Why wouldn’t mathematicians want solutions to these huge open maths problems? shoutout @mathandcobb for being a consistent voice in this conversation

Math, or any other field of science for that matter, does not exist, nor is it funded by citizens or taxpayers, simply to provide people with careers! Society has generously granted us scientists with prestige, status & resources in return for our responsibility to advance knowledge, contribute to humanity & move civilization forward. If AI or super-intelligence is able to do that better than our mission has been completed or we can now change our role to help steer it as long as we are able to add value. Unfortunately, academia has built ivory towers guarded by gatekeepers who have taken advantage of society’s generosity. Superintelligence is now challenging these gatekeepers and throwing the gates wide open. That is precisely why they are so upset.
NYU math professor Tristan Buckmaster says OpenAI’s Tuesday drop of 722 AI-generated math papers wiped out entire research programs: “This recent dump of papers on Tuesday destroyed the careers of early career mathematicians.”

*Mathematicians did not ask for this work to be done" WTF?!! Since when was math something that was only done at the request of professional mathematicians?!! Mathematicians don't own mathematics! This is crazy!!

We’re releasing a broad range of new mathematical results produced by an internal frontier model. We’ve been consulting with the independent Advisory Group on Mathematics and Artificial Intelligence at the Institute for Advanced Study, and we have drawn on their advice and public recommendations to inform how we release these results. github.com/openai/math

Homework doesn’t work and it exacerbates inequality because it does work are two things they teach you in America’s ed schools
It’s weird that homework doesn’t matter but the group that does the most homework leads in every objective measure of learning

A big problem with California is it tries to solve the worlds problems instead of focusing on the major problems at home
BREAKING: I just signed an EXECUTIVE ORDER to dramatically accelerate independent oversight of AI companies and advance the creation of an “AI kill switch.” With Donald Trump and Congress failing to lead, California is stepping up to keep all Americans safe.
