I've warned for months that a @JetBlue-@SpiritAirlines merger would have led to fewer flights and higher fares. @JusticeATR and @USDOT were right to stand up for consumers and fight against runaway airline consolidation. This is a Biden win for flyers! apnews.com/article/jetblu…

@bryan_johnson Did they check for neurotrophic keratisis? Can do simple feather test to check eye reaction or special cornea test that checks irregularity in surface geometry.

We're going around the Moon. Come watch with us. Artemis II's four-astronaut crew is lifting off from @NASAKennedy on an approximately 10-day mission that will bring us closer to living on the Moon and Mars. The launch window opens at 6:24pm ET (2224 UTC).

Ever wondered why basketball players' sneakers are constantly squeaking as they run around the court? Now scientists have studied what's happening and have found the phenomenon is caused by the soft material of the soles rippling on the floor.

I TLDR'ed this for a few friends : - The internet has a lot of data, most of it is not useful for robots, LLMs or RL perception models don't have a physically grounded, world model, in robotics you need an accurate world + physics model -- This is why LLM's are coming for white collar jobs faster than plumber jobs - Many robotics companies started with perception models pretrained on internet data. These are good at identifying what things are (e.g., cars, people) and coarse motion patterns, but struggle with task-relevant geometry, force, and physical interactions when deployed on robots -- If you try to train a human to golf solely with videos, they won't be able to golf very well -- To get a robot (or human) to actually golf, they need to practice golfing - Recent advances in autonomous driving were enabled by massive fleet-scale data collected on production vehicles and used to reduce hard boundaries in the autonomy stack between perception, planning, and control in end-end training - Data is and will continue to be the bottleneck to robotics progress and how the data is collected matters -- Some believe collecting an internet-scale worth of robotics tailored data is required to get a robot capable of generalized tasking and this won't happen anytime soon -- Others believe improved simulation, reinforcement learning, and scaling foundation models will close gap sooner - Standardbots is deploying robots that perform a narrow mission well (95% of the time) that customers will pay for, for the other 5% they teleop into the robot, perform the task, collect data, and update -- Vertically integrating (incl firmware and control over the sensor-to-actuator stack) gives tighter feedback loops, more tunable variables during training, and greater engineering flexibility/margin while they're early in development and learning new use-cases -- They get paid to collect data in an operational environment, incrementally adding narrow tasks performed well while slowly generalizing portions of the autonomy stack

Spend an hour reading this weekend and I think you’ll know more about robotics than 99% of people, including some people who invest in robotics. notboring.co/p/robot-steps

Process was ver silly. We didn’t have mineral rights before, it looks like we will. The RE was unlikely to come out of ground for many reasons ie overreg or we would’ve just bought them, now they likely will and we will secure supply chain for heavy RE critical to defense that China currently controls 90% of supply.

The usual Trump sycophants and know-nothings are all piling in claiming he’s a genius, this is the art of the deal in action, he played hardball to get a better Greenland deal than was otherwise available. It’s all nonsense. In fact, it’s TACO in action, a Trump surrender, a

I’m increasingly convinced that the willingness to change your mind is the ultimate sign of intelligence. The most impressive people I know change their minds often in response to new information. It’s like a software update. The goal isn't to be right. It's to find the truth.

@paulg @lydiamoynihan If you advocate for any policy that would force others to do something that you have the means to do, but are not willing to do so unless others do it. You don’t actually believe in what you are saying.

Regardless of how you felt about Rob Reiner, this is inappropriate and disrespectful discourse about a man who was just brutally murdered. I guess my elected GOP colleagues, the VP, and White House staff will just ignore it because they’re afraid? I challenge anyone to defend it.

Something I’ve noticed going back into engineering that I should have never left: I am 10x more compelled to have uncomfortable conversations I wouldn’t have cared enough to put a lot of thought into to get right in my roles in business I grew bored of.
