Two facts that break prevailing narratives: 1. Manufacturing a cotton T-shirt uses the equivalent water of 1,000 years of ChatGPT usage. 2. Elon musk has paid more tax than any human in history.

If you think mathematicians are having a blast now, imagine how stoked physicians will be once we can automatically diagnose and cure all disease!
It must be so exciting to be a mathematician right now. Imagine spending your life with your colleagues on problems you think will help humanity once solved, and watching them get solved.

If you want to understand why healthcare is so expensive, I'd start with a Supreme Court case about teeth whitening. Around 2003, spas and small kiosks in North Carolina were offering teeth whitening for a fraction of what dentists charge. So dentists complained to the state dental board. That dental board looks like this: - 6 of 8 are practicing dentists, elected by other dentists - 8 of the 10 who sat on the board during this period earned substantial fees from whitening The board sent 47+ cease-and-desist letters, warning non-dentists that they're committing a crime by practicing dentistry without a license. The board also sent letters to mall operators, advising them to expel whitening kiosks. All this worked! These kiosks shut down, prices stayed high, dentists stayed happy. Regulatory capture like this exists all over in healthcare. What makes this case notable is that someone actually sued the NC dental board, in a case that went all the way to the supreme court. In a 6-3 ruling, the SC ruled that if a board is run by those who participate in the market without proper supervision - that looks like a cartel, therefore, antitrust law applies. I have to believe there are so many other potential cases like this in healthcare, just waiting to be pressed on. I'd love to see more of this.

So is Opus 5.5 really generating all these animations without using an image generation API? just by hand? That's wild!

This video inspired me to really push Opus 5.5 and test its limits. I followed the general workflow Donald described here and the results are great
I made this with one prompt using Opus 5.5 I spoke to my computer for 5mins, claude worked for 12 hours, and I woke up to this full prompt:

For years I've been saying the UK tax system is out of control and very wealthy people who pay disproportionately more taxes will leave. When someone like Chris Rokos leaves the UK the money he was paying in taxes (£330M last year) falls on the shoulders of ordinary tax payers. Here's a few interesting points about this story: 1. Rokos is one of the world's best bond traders. His business is to understand how government policy impacts the economy. The fact that he's leaving the UK is a massive signal - he sees a negative outlook in the UK. He sees that we will go down the disastrous path of wealth taxes, exit taxes and become even more anti-wealth and anti-success than we already are. 2. A move like this has a lot to do with his senior team. Chris would have a dozen senior partners in his organisation that are fed up with the UK too. Each of them worth £100M+ or making £10M+ income. They would also be driving this decision. When the Greek authorities rolled out the red carpet, the London office would have talked it through as a team and decided where they wanted to be. 3. Big Whales make the headlines but this isn't one guy leaving. The news isn't covering the thousands of people leaving the UK who make £1M per year or who are taking their £10M of capital somewhere else. It certainly isn't covering the complete stop we've seen in entrepreneurs coming to the UK to invest. 4. Your idealistic feelings don't matter. Many people say "good riddance" and this is utterly foolish. We live in the real world and gleefully celebrating wealth creators leaving the economy is akin to a business celebrating their top customers taking their business elsewhere. The people leaving were not avoiding tax - if you could stay here and avoid tax then they wouldn't leave. The people leaving were paying MASSIVE amounts of tax but they got pushed too far. No one wants to pay 5-star prices for a 3-star service. You can call him "greedy" but until I see you happily paying a million a day I'll assume that all people are self interested. 5. The UK Government is genuinely broken and needs fixing. We pay more in welfare than the entire income tax collected. We let government pay 10x more for things than the private sector would allow. We have a revolving door between government and the contracting class who extract money from government. If you ran your business like the UK Government, you'd be broke in no time. Like it or not, we live in a competitive world with a hyper-mobile class of wealthy people. Each country must choose to become a destination or it will be a departure gate. Greece has shown its cards - it's playing to win and rolling out the red carpet for wealth creators. The UK is deliberately playing a strategy that is proven to lose and shouldn't act surprised when it unfolds the way it always has. ft.com/content/43efa6c1-6b37…

I've been a software engineer for over twenty years. I can tell you, Fable is something else. It is incredibly good at writing code. The world is about to change. Also we need some OpenAI competition because it is SO expensive.

Fable 5 is wild to use. I'd go as far to say it's automated software engineering.
