The fact that something hasn't been done is not necessarily evidence that it won't work. A few years ago you could have asked why everybody was still using disposable rockets, if reusables would be so great. And coal is not exactl

And because if you build a lot of reactors, then you get a learning curve where they get cheaper over time, just like any other mass-produced item. Some of the SMR designs can even be built in factories. The article ignores this, and in f

According to Isaacson's biography, that's exactly where the idea came from, Hotwheels and all. Even if they don't manage it for the whole car, it does seem to have worked out for the front and back castings, since other compa

Lately the traditional auto makers have been ramping down their BEV production. Besides less competition, extra benefits to Tesla include battery prices going down and more income from selling regulatory credits.

I lived in Europe back in the '80s, and streetcars were quite common at the time. I spent at least as much time on them as I did on buses. (Whether it's different now, I don't know.)

Lab-made diamonds are common in jewelry these days, and generally cheaper than mined diamonds. I bought some from Belk recently.

I know what you mean but "we're safe until we go extinct" doesn't give me warm fuzzies :)

I just assumed it was a metaphor for runaway climate change, which they didn't want to spell out because of the political noise it'd generate. Just like in Matrix I assumed that the nonsensical "humans as energy source"

On the first point about the "aging models," the Model Y is currently the best-selling car in the world, outselling much cheaper cars. It doesn't seem like it's in dire need of a refresh. The Model 3 isn't far behin

From a glance at their financials, they have $29 billion in cash, $9.5 billion in debt, and positive cash flow of $4 billion annually. Why would they go belly up?

I'm aware that Reagan maybe had that attitude in general but I don't see it in this particular letter. He mentioned lack of available funds due to an excess of disasters, and promotes volunteerism, which I'd say is a pretty i

I might not understand your concern but to me this seemed clear enough: > The first stage is an airship that travels from the ground to 140,000 feet. There it will dock with a waystation floating at the top of the atmosphere. Cargo and c

Ethereum would not stop working just due to a price crash. It would get cheaper for an attacker to purchase majority stake, but good luck purchasing that much without making the price go back up.

Not at all. The validators get a small portion of the transaction fee for themselves and certainly they could ask for something different. But the ETH burn is built into the protocol. In theory that could be changed, if you got agreement no

You need ETH to pay transaction fees. As long as there's more demand for blockspace than the space available, ETH will have a non-speculative value. The reason for the burn was the 1559 upgrade, which fixed the horrible user experience

Key redundancy and social recovery are pretty much solved problems in crypto.

ETH is not a memecoin and it has a real economic model. It's used to pay transaction fees, which are mostly burned. There's a small amount of issuance but most of the time that's less than the burn, so the supply shrinks. You

Mine is also in the countertop, makes sense that code would require it in that case. Previous owner didn't like the idea of wet hands on a wall switch.

What I'm talking about is an electric grinder that that sink drains into. Lots of people have them in the US.

The bumpers are also massive. They're large concrete pillars. Here's video showing what they look like on similar bridges around Baltimore. https://www.youtube.com/watch?v=dFl412SuWZE&t=41s

Yeah I'm guessing just replacing the bridge will cost a lot more than the bumpers would have, even without counting the broader impacts.

According to this Baltimore news report, after 9/11 state officials had looked at putting bumpers around the piers that could have protected the bridge from an impact like this, but it was too expensive. https://www.youtube.

So it's a bit more than a 10X size increase. But 20 years ago we were using cryptography without it being an undue burden on the network. How much more bandwidth do we have now? How much more storage? Even on phones without wifi availa
