Never mind about the Rolex… had no idea buying one was like buying a Ferrari, where you have to beg, jump though hoops and then buy products you don’t want to get the one you do want! 😂 thought it would be fun to own, but would much prefer to just order something on a website (like a Tesla!) and be done with it. These retail and reseller channels make things far too time consuming Is there a nice watch I can just… order?
@jason@Jason

I would like to purchase this @ROLEX

@mattyglesias What?? Who doesn’t love to laugh? Also I interpret this as “shared sense of humor” not “funny like a comedian”

@AOC @NPC92846601 Clark County School District + Nevada State cost Medicaid 5x more than Tesla. And Tesla only costs nevada 6M in medicaid costs. Doesn't seem like a huge subsidy.

@NPC92846601 In the state of Nevada alone, Tesla is one of the corporations that ranks *highest* in Medicaid costs, which is another form of public assistance program. That’s on top of the $330 million they’ve already received in state public dollar tax incentives. rgj.com/story/news/mon…

The single largest form of theft in America is wage theft. $50 billion a year are stolen from American workers. If a billionaire amasses their wealth by underpaying their full-time workers so severely that they must rely on food assistance and government programs to survive, then no, that wealth was not earned by one individual - it was a wealth transfer subsidized by underpaid American workers and the public who get stuck with the bill for large corporations free-riding off our systems. The point is less about individual morality. It’s more about how our current economic reality of shattering inequality rewards screwing over workers and exploiting essential systems at scale. We’re talking monopoly power. Rent-seeking. Wage theft. Profiteering. Stock buybacks. Destabilizing housing markets. Companies using SNAP/EBT to underwrite their wages. Massive government subsidies or contracts to corporations following lobbying and dark money in politics with little to no oversight or accountability. Some people get enraged that I draw attention to this. That’s on them. Let them call me shrill, dumb, inexperienced, girly, uneducated - these folks will say anything to distract from or undercut the truth that working people are getting screwed, and giving people a fair shake means we must have a grown conversation about reigning in abuse of power.

AOC: “There’s a certain level of wealth and accumulation that is unearned. You can’t earn a billion dollars. You just can’t earn that. You can get market power, you can break rules, you can abuse labor laws, you can pay people less than what they’re worth, but you can’t earn that”

@Brad_Setser @mattyglesias Poor theory, private investors understand a business is more volatile with more leverage. That's just business fundamentals and PE investors are not stupid.

Brad Setser@Brad_Setser·
@mattyglesias theory is that "private" holders don't have to worry about the extra volatility in the stock price that can come with more leverage. Tis an intrinsic part of the model as you know; early "PE" firms were rebranded leveraged buyout firms

We're building a version of @karpathy 's autoresearch to help us predict prediction market prices and, ultimately, forecast the world more accurately. Good news: it has improved its accuracy over time! Bad news: it's done that by giving up, removing predictive features, and just using the previous market price as the predictor. We've got some more work to do! This is only week 2, so we've got plenty of room to run.

What happens when you let an LLM autonomously improve its own prediction market strategy for 9 days straight? It learns to give up. Me and @ahall_research worked on a LLM pipeline on Polymarket (Bitcoin, NYC weather, miami weather) and every 4 hours it made predictions. Every night a separate AI reviewed performance, picked one thing to change and committed code. No human in the loop. Timeline: - Day 1: It added confidence prompts - "don't hedge, commit to your prediction" - Day 2: It turned down the shrinkage parameter that pulls predictions towards market consensus - performance got worse - Day 4: It reversed course and turned shrinkage back - Day 6: It tried a clever prompt trick for weather contracts (also made things worse and got autoreverted) - Day 7-9: It stopped changing anything By the end, the squared error was down 54%. This sounds impressive until you realize that the improvement came almost entirely from the system learning to deviate less from market prices. The self improvement loop worked perfectly as engineering but the problem is that the underlying system doesn't have an information edge on any of these contracts since it's reading the same news the market already priced in. To actually beat the market, the system would likely need faster or better information or contrarian accuracy (i.e., correct predictions specifically in the cases where the market is wrong).
