It's much harder to determine motive (which only exists in Mark Rober's mind) than to determine whether a video is misleading. You can look at Rober's Youtube video, compare it to the unedited video (which he only posted on T

The first tweet I linked to is Mark Rober's unedited video of the crash. The second tweet I linked to is a video of someone trying to reproduce the Wile E. Coyote test. Unless you think the videos are faked (one of which was posted by

Mark Rober's video is misleading. First, he used autopilot, not FSD. Second, he sped up to 42mph and turned on autopilot a few seconds before impact[1], but he edited the Youtube video to make it look like he started autopilot a from a

Starship development has been funded mostly by SpaceX, not by the US government. SpaceX did win a contract for the Human Landing System, but the payouts are contingent on certain milestones, such as demonstrating in-orbit refueling. Also mu

Splitting water is only one step in getting electricity to move a hydrogen fuel cell vehicle's wheels. Compressing hydrogen is around 90% efficient. Fuel cells in vehicles are around 60% efficient at converting hydrogen and oxygen to e

The efficiency of using electricity to split water, then compressing and transporting the hydrogen, then using that hydrogen in a fuel cell to power an electric motor, is much worse than using electricity to charge a battery to power an ele

A typical car alternator outputs 1.5-3kW of electricity, and EVs can output arbitrary amounts of power for electronics (though that will reduce range). That's more than enough to run purpose-built circuitry for a SOTA LLM. For a home r

The wipers are certainly better than when I got the car 5 years ago, but they still seem to go too slow or too fast in some conditions. I don't have much to compare them against, as my previous cars have all been from the early 1990s o

That's odd. I live in the Pacific Northwest and I can count on one hand the number of times I've had to manually turn on defogging. Often my Model 3 will say, "auto defogging". Maybe your humidity sensor is faulty? I agr

I'm guessing you meant the Nuclear Regulatory Commission, not the National Reconnaissance Office. Considering that since the NRC was created in 1975, no nuclear plant license initially submitted to them has begun commercial operations,

This is not correct. SpaceX is covered by ITAR and therefore cannot hire foreigners. Of the approximately 70,000 Tesla employees in the US, fewer than 2,000 are H-1B workers. The rest are US citizens or permanent residents. Tesla's man

Self-driving makes the most economic sense when fewer people are in a vehicle. With a large van or bus, the cost of the human driver is split between more passengers. Also van or bus service is less compelling to individuals, as it makes th

The camera, mouse, and monitor all stayed the same for the tests, but there was a significant difference in latency. Out of the 16 times the experiment was run, only once did Wayland have lower latency. It would be an amazing coincidence if

Sourcing hydrogen from electricity means splitting water and compressing the hydrogen. The electrolysis step is around 50% efficient, and compressing the hydrogen for storage takes some energy as well. If the light cell is 50% efficient at

For SpaceX to keep up their current launch cadence without reusability, they would need to build a new Falcon 9 booster every 2-3 days instead of every two months. It would also require an 8x increase in their build rate of Merlin engines.

If you're going to blame anyone for that, blame CPUC. They're the ones who dictate what rates PG&E can set, what their yearly revenue should be, and what they're allowed to modernize. This often causes problems, such as i
