La relación entre Cheo Feliciano y Tite Curet Alonso trascendió ampliamente lo profesional. De acuerdo con algunas fuentes, se conocieron en Nueva York en 1960, en el bar El Gallo de Oro, y según el propio Tite hicieron amistad casi de inmediato. Curet admiraba la manera de cantar de Cheo, lo aconsejó desde aquellos primeros años y vio en él el potencial para convertirse en una gran figura solista; una confianza que Cheo correspondió siguiendo sus consejos.

Esa amistad se mantuvo durante décadas y terminó convirtiéndose también en una extraordinaria sociedad artística, en la que Tite escribió para su voz piezas fundamentales como ‘Anacaona’, ‘Mi triste problema’, ‘Juan Albañil’, ‘Los entierros de mi gente pobre’, entre otras, llegando incluso a intervenir directamente en proyectos destinados a relanzar su carrera, una relación de amistad y compromiso que convirtió a ambos en una llave exitosa dentro de la música caribeña.

Stanford professor Judy Fan went on stage at MIT and broke down why humans are so good at making the invisible visible...

And why AI hasn't actually learned to "see" the way we do.

It completely changes how you think about Human Intelligence v/s Artificial Intelligence:

1. Nature never gave us straight lines or sharp corners. The number line, the coordinate plane, even basic geometry are all human inventions. We created tools that do not exist in nature simply because we needed a way to think more clearly.

2. The coordinate system Descartes invented solved a problem that had stumped mathematicians for centuries, doubling the volume of a cube. Once invented, this tool became so indispensable that virtually every math curriculum on Earth still depends on it.

3. Humans have been doing this for at least 30,000 to 80,000 years. The story of human progress is inseparable from the story of marking up our environment, from cave walls to Galileo's telescope to Feynman diagrams of particles we will never see with our own eyes.

4. Every major scientific breakthrough relied on a visual tool that made something invisible visible. Darwin needed side-by-side illustrations of finches to see variation that was otherwise too subtle to notice. Cajal needed detailed drawings of neurons under a microscope to map how the nervous system was wired.

5. Fan's research group studies something deceptively simple: how people decide what to put into a drawing and what to leave out. When two people played a drawing game, sketchers used far more detail when the target object had close competitors than when it stood alone, all the way down to using fewer strokes and less time when more detail was not necessary.

6. People are not just copying what they see. They are making constant judgment calls about what level of detail actually serves the goal of communication, and they do this naturally without ever being taught the theory behind it.

7. There is a real difference between drawing something so someone can identify it and drawing something so someone can understand how it works. In one study, participants drew explanatory diagrams that emphasized moving, causal parts of a machine while depictive drawings emphasized background and overall appearance, even though both were drawing the exact same object.

8. Explanatory drawings were genuinely better at helping someone figure out how to operate a machine, but worse at helping someone identify which machine it actually was. You cannot optimize a single drawing for both goals at once. Communication always involves tradeoffs.

9. AI vision models trained on photographs generalize surprisingly well to simple, sparse sketches, suggesting that resemblance based recognition is not just a story we tell ourselves. It is something modern neural networks can replicate with real accuracy.

10. But there remains a large, measurable gap between how confidently AI models recognize sketches and how confidently humans do, even when both groups answer the same questions about the same images. Humans are simply far more reliable and far more consistent in their judgments.

11. When researchers compared human-made sketches to AI-generated sketches under tight stroke budgets, both were similarly recognizable at higher budgets, but diverged sharply as the budget shrank. Humans and AI systems simplify drawings in fundamentally different ways once resources get scarce.

12. Reading a graph is not one single skill. It involves perception, knowing where to look, mapping that visual information onto the actual question being asked, and then translating that mapping into an answer. Each of these steps can independently break down, and people fail for very different underlying reasons even when they land on the same wrong answer.

13. When tested directly against humans on graph reading tasks, leading multimodal AI models, including GPT-4V, showed a meaningful performance gap. Even when a model's overall accuracy approached human levels, its pattern of mistakes looked nothing like how humans actually get things wrong.

14. People choose entirely different types of charts depending on what specific question they are trying to answer, not out of a generic preference for bar charts or scatter plots. Their chart choices closely tracked which visualization would genuinely help someone answer that specific question correctly.

15. Two of the most widely used graph literacy tests in education research turned out to correlate strongly with each other, suggesting they measure overlapping skills. But when researchers dug into the actual error patterns, the standard categories used in textbooks, like "find the maximum" or "identify a cluster," failed to explain why people got things wrong nearly as well as a more basic, underlying four-factor model did.

16. The deepest goal behind all of this research is not just academic curiosity. It is to eventually help students and everyday people develop genuine literacy with the visual tools that science and modern decision-making increasingly depend on, because every generation should be able to see further than the last by standing on the visual tools the previous generation built.

Jeff Bezos on the 4 principles that differentiated Amazon from other companies

“The thing that connects everything that Amazon does — our #1 conviction, philosophy, and principle — is customer obsession, as opposed to competitor obsession. We are always focused on the customer, working backwards from the customer’s needs, and developing new skills internally so that we can satisfy what we perceive to be future customer needs.”

Jeff Bezos continues:

“It seems like we’re in a bunch of different businesses. We have Amazon Web Services, which is completely different from our Amazon Prime business or Amazon Marketplace or Amazon Studios and so on. But really the way that those businesses run are very similar, and it all starts with customer obsession. But it’s not just customer obsession.”

Pioneering is another critical principle for Amazon:

“We have a very inventive culture. We like to pioneer and invent. There are other very effective business strategies. Pioneering is not the only effective business strategy. In fact, some people would argue it’s not the most effective one. Close-following can be a very good business strategy, and it’s worked many times if you look at the history of business. But it just isn’t who we are.”

Willingness to think long-term is another one:

“That’s another common thread that runs through everything we do. We are very happy to invest in new initiatives that are very risky for 5-7 years. Most companies won’t do that. Companies will invest for very long periods of time in the cases where the outcomes are more certain, but it’s the combination of the risk-taking and the long-term outlook that make Amazon special.”

Taking pride in operational excellence is the final one:

“Doing things well. Finding defects and working backwards. That’s all the incremental improvement that most successful companies are very good at. If you’re not good at finding the root cause of defects and fixing that root cause — you don’t ever want to let defects flow downstream — that’s a key part of doing a good job in any business, in my opinion.”

On April 1, 1999, Mark Cuban sold a streaming company called Broadcast .com to Yahoo for $5.7 billion. He became a paper billionaire overnight.

Yahoo had paid him in stock, not cash.

He spent the next 6 months trying to figure out how to keep it.

Cuban owned about a third of Broadcast .com going in, which left him holding 14.6 million Yahoo shares worth roughly $1.4 billion at the time. By law, he couldn't touch any of it. The deal came with a standard 6-month lockup that prohibited him from selling or hedging a single share. He had to sit and watch.

What he watched was a tech market getting more disconnected from reality by the week. Companies like Pets .com and Webvan were burning through investor money with no path to profit and trading at valuations that didn't make sense to anyone who looked twice. Cuban looked twice. He decided the crash, when it came, was going to take everything down with it. Including Yahoo. Including him.

So he started planning.

The moment his 6-month lockup ended, Cuban put on a financial structure that's now famous in trading circles. A zero-cost collar.

A collar works like this. You sell call options on your stock, which gives someone else the right to buy your shares from you at a fixed higher price. That caps your upside. You use the cash from selling those calls to buy put options, which give you the right to sell your shares at a fixed lower price. That gives you a hard floor under the downside. The two trades balance each other out so the whole package costs almost nothing to put on, hence the name.

Effectively, Cuban locked in something close to his $1.4 billion. If Yahoo's stock went down, his puts paid out. If it went up, he'd hit the cap and be cashed out at the higher price.

Yahoo's stock kept rising at first. It hit his cap. He got cashed out, in cash, at the high level he'd set. Real dollars, not paper.

A few months later, in March 2000, the dot-com bubble burst.

Yahoo's stock fell from a peak of roughly $237 a share to about $13 over the next 2 years. Almost every other dot-com paper billionaire watched their fortune disintegrate. Many of them had not hedged because they didn't think the prices would fall, or because they thought hedging was a sign of weakness, or because they were emotionally attached to the company they'd just sold.

Cuban kept his $1.4 billion. He once called the trade "one of the top 10 trades of all time on Wall Street."

People remember the sale. They don't remember the collar.

The headline was the $5.7 billion sale to Yahoo. The thing that actually mattered, the move that decided whether Cuban kept his fortune or watched it disintegrate like everyone else's, was a piece of derivative paperwork most people couldn't even read.

Plenty of founders sell at the top. What separated Cuban is that he understood selling was only half the trade. What you do with the money in the moments right after the windfall matters more than the windfall itself.

Cuban put it more simply.

"The whole market cratered and I was protected."
