Adelson's illusion

Demonstrates the subjectivity of our perception quite vividly. We can understand with our minds that the squares are the same, we can measure their sameness with an instrument, but we perceive them, nevertheless, as different. That is, we "clearly" see something that does not really exist.

Elon Musk:

I see poverty as more of an engineering problem than an unsolvable social issue. With Grok and Optimus, we could solve the labor shortage, drive costs to near zero, and create a future where poverty is statistically irrelevant.

The scale of whats coming over the next decade is really easy to underestimate.

Agility has announced a major milestone: Digit robot has moved over 100k totes in live operations at GXO Logistics’ facility.

This comes just days after Figure's CEO predicted Agility's bankruptcy within 12 months, and one day after Figure announced 90k parts loaded at BMW.

Elon Musk: In the future, there won't be operating systems or apps.

“In the future, there won't be operating systems or apps. It'll just be a device that is there for the screen and audio and to put as much AI on the device as possible to minimize the amount of bandwidth that's needed between your edge node device, formerly known as a phone, and the servers.

You'll get everything through AI. Whatever you can think of, or really whatever the AI can anticipate you might want, it'll show you. That's my prediction for where things end up, in probably five or six years.”

Why Elon Musk said Quantum computing is best done in the permanently shadowed craters on the Moon?

At first, it sounds like one of Elon’s wild sci-fi ideas, but there’s deep logic behind it. Quantum computers need extreme cold and perfect stability to work. The Moon’s permanently shadowed craters, like Shackleton, stay at −200°C, with no atmosphere, no noise, no heat, and no weather, the ultimate natural lab for quantum physics

On Earth, we spend millions creating those same conditions artificially. On the Moon, they already exist Once again, Elon isn’t daydreaming, he’s pointing at the future.

🇨🇳 In China, parents are turning AI into a real-time study supervisor.

They open ByteDance’s Doubao, point the camera at their child, and issue a simple command: “Doubao, keep an eye on him. Warn him if he loses focus or slouches.”

From there, the assistant takes over offering a steady stream of corrections:

“Stop fiddling with the pen.”
“Focus on the assignment.”
“Sit up straight.”
“Don’t doze off.”
“Don’t lean on your hand.”
“Quit chewing the pen.”

It’s AI as a digital study hall monitor.
