I was addressing the comment about the economics of lower launch costs, not space debris. Similar to past pollution issues, I think it will be a problem but not a show stopper. There are already global standards for satellite end of life pr

A lot of the damage happens as soon as the spacecraft enters the water, because it's extremely hot, causing more chemical reactions than you might think. Even jet engines have trouble with corrosion from ingesting small amounts of aero

Doesn't this argument prove too much? Long ago, compute was extremely expensive. The cost of compute went down, but people made tons of money selling more and more computers. The same was true for most technologies when they were first

The Wikipedia article says 22 of the 36 became pregnant with a fellow crew member during the deployment. All of them had to be transferred off the ship so they could be closer to an obstetrician in case of complications.

Pregnancies become a bigger problem on submarines because of the limited space for medical facilities and the difficulty of transferring crew on/off the sub.

I do shooting competitions from time to time, and I agree that Olympic target shooting has too much strange equipment. Most great shooters don't even bother with it because it's so boring and equipment-specific. Instead they do st

In Australia, self-driving features beyond lane keeping are banned, and lane keeping is limited to imparting a maximum lateral acceleration of 3 meters per second squared. Because of these restrictions, all Teslas in Australia are using a g

I bought a Model 3 back in 2020 and got the self-driving option mostly on a whim. Until recently, it was a handy feature on freeways but a gimmick on surface streets. Ever since the update a couple months ago, it actually does drive itself.

That's why you click on the "Following" tab, not the "For you" tab. Also, how is that any different from any other social media platform? Heck, I just opened Apple News and it recommended me a Buzzfeed article title

They got those domesticated breeds from agricultural societies. The only example of an animal domesticated by hunter-gatherers is the dog.

Horses were domesticated long before the Magyars showed up. It’s much easier to selectively breed horses if you start with domesticated ones.

by chroma 2y ago
Agriculture is almost certainly a prerequisite to domesticating horses (as they must be selectively bred in captivity), so hunter-gatherer tribes like the Clovis never had a chance to do so.

Can you link to the post about that? Because I’m guessing there’s a selection effect where only those who had profound experiences commented. I’ve done similar things in VR and found it wasn’t any different than when I had a robot body or a

The regulations are different. The FDA only gets in trouble if they approve a drug that turns out to be harmful, not if they fail to approve (or delay approving) a beneficial drug. On net, the FDA has caused far more harm than they’ve preve

Where can I read more about this? If that’s true, it seems like a problem of over-regulation, not drug companies being exploitative.

Semaglutide was invented before 2008. Its patent expires in a few years. It takes a long time to get drugs through trials and get the FDA to approve drugs for new uses. Pharmaceutical companies spend billions on drugs that never make it thr

Probably never because every generation of Starlink satellite has been dimmer than the last. Despite being significantly bigger, the v2 minis are only 19% as bright as the original satellites.

I think a lot of men don't realize that for most women, the feeling of walking around alone in a normal place is equivalent to a man walking around in a very sketchy neighborhood. Almost any man can overpower a woman and, if he really

This sort of thing happens all the time in SF. There are a lot of crazy people in some areas of the city. If you stopped for every one of them (even the ones a lane or two away) you’d never get anywhere. Heck, I’ve had someone run in front

Tesla offers three tiers of automated driving: Autopilot. This automatically accelerates, decelerates, and steers on roads. This works on all roads with lane markings, not just limited access freeways. It also obeys speed limit signs. Enhan

You could look at liability insurance rates. If the same driver has a lower insurance rate for a car with a certain automated system, then that system probably makes driving safer.

China is the same size as the US but has four times the population, and most of them are in the east. This means they have much higher population density. Another important difference is that they can build rail for much cheaper than the US

I've never gotten to an airport two hours ahead of my flight, not even for international travel. For a short, frequent flight like SFO-LAX, I arrive at the airport 15 minutes before boarding starts. I'm not at all worried about mi

Air travel is 2% of global CO2 emissions. Making air travel carbon neutral (by capturing carbon) would increase ticket prices by around 20%. That would be much cheaper than switching from planes to high speed rail. I'm not saying that

I didn't say anything about roads, but it's not true that roads are unprofitable. Roads are paid for by fuel taxes and vehicle registration fees. California's gas taxes raise $8 billion per year. The state's registration

The distance between SF and LA (350 miles) is 50% greater than the distance between Tokyo and Kyoto (227 miles), making the time tradeoff favor trains to planes. The two cities are much bigger than SF and LA, so many more people travel betw

High speed rail between San Francisco and Los Angeles isn't economically viable. California HSR will cost at least $30 billion to construct and California's own estimates claim it will cost $700-$874 million per year to operate.[1

HSR only makes economic sense in the northeast. Everywhere else is too spread out for rail to compete with air travel. The most popular air route in the western US (SF-LA) isn’t worth making high speed rail between. The project is expected

TSA can screen people the same for rail, they just tend not to. Ideally we’d go back to pre-9/11 screening for everything.

You can charge Teslas at other charging stations. It’s just that other chargers are inconvenient and unreliable. You usually need an adapter. You have to pull out a credit card and maybe install an app on your phone. With the Tesla chargers
