I’m in love with this sentence:
“The best math you can learn is how to calculate the future cost of current decisions.”
English
@elonmusk Interesting concept to think of it that way.

@cooltechtipz These are good reminders.
Most of social intelligence just comes down to this:
learning to stay open when your instinct is to protect.
The moment you stop taking things personally, you start seeing clearly.

Most people try to master money before mastering their own mind.
Turns out they’re the same problem.

Working optional sounds clean until you remember building is human nature.
We won’t stop. We’ll just build for different reasons.

Elon Musk describes AI as a "supersonic tsunami" that will overtake digital jobs "like lightning." He expects physical jobs, like cooking, plumbing, and electrical work, to exist for much longer. He predicts that ultimately AI and robots combined will make working optional.

The truth is, every so called “bubble” teaches us something we couldn’t learn any other way. Bubbles don’t pop everything. They leave lessons and that’s how the world actually changes.
Money builds the machines. Mistakes build the mindset.

Jeff Bezos just explained the “AI bubble” better than anyone. At Italian Tech Week 2025, Bezos didn’t deny the hype, he embraced it. “Yes, there’s a bubble. But AI is real and it’s going to transform every single industry.” He called it an industrial bubble, not a financial one. That’s a crucial difference: •A financial bubble (like 2008) destroys value and leaves nothing behind. •An industrial bubble (like AI, the internet, or fiber optics) creates massive value, even if investors get crushed. “Even when those companies went bankrupt, the fiber stayed in the ground. Society got the infrastructure. That’s what we’ll see with AI.” Bezos says right now we’re in the “chaotic, beautiful” phase of overfunding, where every wild idea gets money. Investors can’t tell the good ideas from the bad ones. But that’s exactly how big shifts happen. He compared it to Amazon’s early days: “Our stock went from $113 to $6, while every internal metric improved. The market and the reality had completely diverged.” His point: bubbles distort prices, not progress. AI valuations might crash, but the technology won’t. “This is not a mirage. This is a horizontal technology, like electricity and it will touch everything.” Bezos isn’t predicting an apocalypse. He’s predicting a reset, where the hype burns off, and the real builders remain. AI isn’t a bubble, it’s a boom disguised as one.

@karpathy @GoodFaithOnly @binarybits Love this framing. Capability isn’t diffusion.
AGI is feature complete cognition. ASI is recursive integrative deployment across society. The bridge between them isn’t scale, it’s feedback.
English
When I say AGI I mean a "feature complete" build of a remote worker with a lot of 9s (think: a bit like current Autopilot FSD, maybe plus a few more iterations). This is the original definition I've stuck to forever. Separate from the diffusion /implementation of it across society (the point where every single car on the road is fully autonomous). An industry-wide adoption of AGI I would personally then term ASI. I wrote a bit more here earlier:

@ID_AA_Carmack This is exactly what most people miss: autonomy isn’t binary. You’re describing the ethical scaffolding of machine learning - reality anchored apprenticeship before independence.
Every system starts as remote operated reality and climbs the ladder of self-trust.
English
Companies selling the dream of autonomous household humanoid robots today would be better off embracing reality and selling “remote operated household help”. Have teams of employees running them 24/7, with the option to reduce their workload as autonomous behaviors become viable. That would be genuinely valuable for some people, although likely still a money sink even with low cost labor. It would be the ethical way to gather the desired training data.

✨The Hidden Variable in the Rocket Equation
Rocket equation punishes fuel, not infrastructure.
Three levers beat the exponent: subtract km/s (skyhooks/loops), raise vₑₓ (beamed/nuclear-thermal), or offload energy to the grid.
+15% g → ~22% ↑ mass ratio—erased by a 3–5 km/s skyhook or Isp ≈ 900 s. Infrastructure wins.
@grok What are your thoughts about this framework?

This morning's Launch Readiness Review gave a unanimous GO for Atlas V to launch one of the most sophisticated and powerful commercial communications satellites ever deployed -- the ViaSat-3 F2 ultra-high-capacity broadband spacecraft.
Launch will occur Wednesday from Cape Canaveral during a 44-minute window opening at 10:24 p.m. EST (0324 UTC).

Starlink is improving fast

STARLINK SPEEDS UP – 50% FASTER, AND V3 HASN’T EVEN LAUNCHED YET Starlink’s turning “high-speed” into an understatement! Speed Stats: • Median speeds up 50% since January • 200+ Mbps downloads, 30+ Mbps uploads • 26 ms latency – faster than most fiber And this is all before Starlink V3 even hits orbit!

@theallinpod @elonmusk Between the denial and doom lies real data.
Climate change isn’t belief. It’s just chemistry over time.
The solution isn’t panic or apathy, it’s calibration.
Measure → adapt → sustain. Let science, science.

Elon Musk: Bill Gates is “not strong in the sciences.”
“I just wanna say, Billy G is not my lover.”
“You'd think that someone like Bill Gates, who started a technology company that's one of the biggest companies in the world, Microsoft, you'd think he'd be really quite strong in the sciences.”
“But actually, he is not strong in the sciences.”
“The reality of the whole climate change thing is that you've just had people who say it doesn't exist at all, and then people who are super alarmist saying Florida is going to be underwater in 5 years.”
“And obviously neither of those two positions are true.”
“The reality is, you can measure the carbon concentration in the atmosphere.”
“At some point, if you continue to take billions, eventually trillions of tons of carbon from deep underground, and transfer it to the atmosphere and oceans, you will change the chemical constituency of the atmosphere and oceans.”
“You just literally will.”
“And the reality is that, in my opinion, we've got at least 50 years before it's a serious issue.”
“I don't think we've got 500 years, but we've probably got, you know, 50. It's not 5 years.”
“The concern level for climate change is on the order of 50 years. It's definitely not 5, and I think it probably isn't 500.”
“So really, the right course of action is actually just the reasonable course of action, which is to lean in the direction of sustainable energy.”

Starlink isn’t just internet from space anymore. It’s really proof that connection no longer has a zip code .
A dish on a roof means a student can learn, a builder can sell, a dreamer can join the conversation.
Connectivity used to depend on cities.
Now it depends on vision. It’s so great to be alive during this time. 🌍

In science terms, he’s turning tacit creator pain into structured insight. It’s brilliant.
What he’s really describing is a four-step knowledge extraction loop:
1. Identify the recurring problem signals - language of pain.
2. Clarify them into precise categories - payments, retention, access.
3. Validate the simplest actionable truth - speed > complexity.
4. Evolve it through distribution - teach by doing, every day for 30 days.
This in principle will generally help across all domains. Getting rich is just a possible by product of this framework.

Facts 💯 If you think about it, every biological system is an adaptive algorithm.
Uniform prescriptions collapse under genetic and environmental variance. Human optimization cannot be standardized for these reasons.
The best practice model would be observe → adjust → measure → evolve. Run your baseline, apply one variable, measure the delta, iterate. Our biology is a living model and doesn’t organically fit the cookie cutter health model we have today.
English
most health advice is anecdotal because it doesn’t account for the full spectrum of human genetics. some people could literally be harmed, or even die, on a vegan diet, while others might feel terrible on a carnivore diet. the only way to know what truly works for you is to experiment and get regular tests to monitor how your body responds

I experienced absolute no difference in sleep and life quality whether I:
- drink coffee first thing in the morning or delay it
- drink it on an empty stomach or after breakfast
- have dinner 3 hours or 30 minutes before sleep
- drink alcohol before sleep
- eat a lot of carbs or only protein before sleep
If I have caffeine after 4pm my sleep is bad. But I have friends who drink espressos before sleep.
I think these sleep and life hacks are mostly (like almost every health advice on this app) anecdotal. They vary by individual. Test what works for you.
