I credit most of SpaceX's success to CEO Gwen Shotwell. She keeps things going even when Musk is off on an irrelevant tear somewhere else.

Unfortunately, Musk seems to be on a path to sabotaging her efforts. The SpaceX prospectus showed that xAI (which bought Twitter, because why not?) was the reason they posted a loss in the last fiscal year. Even with all the expenditures on Starship, SpaceX would have been profitable. Like every other major AI company, it is not at all clear that xAI can reach profitability anytime in the near future, especially since xAI is blocked from so many enterprises and doesn't seem to be able to keep up with the big three at all. As Starship production scales up, the costs are going to increase, and they need payload revenue to offset those costs. There's so much focus now on the Pez dispenser and the lunar mission that I haven't seen any hints of the conventional payload delivery version (aka, "Chomper") in a couple of years. Maybe it's being quietly worked on. I hope so, because the big space station payloads that were talked about a few years ago will need it.

It seems like it should be just theming, but there's a separate architecture to it. Even the APIs are different, with new using a GraphQL-based API and old using a more traditional structure. The core data (users, posts, comments, etc.) is the same, but the pathways are completely different. New has links into capabilities that old doesn't have (especially around abuse and scraping), and old has capabilities that new doesn't always have (especially around mod tools, which new apparently breaks on a regular basis).

When they do get rid of old I think that is going to be it for many users, me included.

"Many users" is going to be relative. I saw some numbers recently that only around 1% of users go through Old Reddit, and in many of the largest subs, it's a fraction of a percent. I don't think it will have the impact that some people think. I prefer Old Reddit on desktop, but it's clunky on mobile, so I stick with the new interface (I don't use the app).

For global energy, that typically includes transportation. As more economies have expanded, there has been more use of cars, trucks, trains, ships, and aircraft, almost all of which are powered by fossil fuels.

Global electricity generation has changed. In 2000, 64.1% of global electricity came from fossil fuels, 16.7% came from nuclear, and 18.7% came from renewable. In 2023, despite overall electricity generation roughly doubling, fossil fuel generation was down to 60.1%, nuclear was down to 9.1%, and renewables were up to 30.23%. Looking at the renewable mixes, in 2000, it was 17.4% hydropower, 0.7% biofuels, 0.2% wind, 0.01% solar, and 0.3% geothermal. In 2023, it was 14.6% hydropower, 2.2% biofuels, 7.75% wind, 5.4% solar, and 0.3% geothermal.

That's still a lot of fossil fuel electricity generation, but it is declining by percentage and their growth curves are flattening. Renewables are up by quite a bit and still growing. Nuclear is declining, and isn't likely to recover in any meaningful numbers. This program is a lot like past programs meant to encourage new nuclear power plants. Odds are that maybe one will get started, and it might not get finished.

the longest, most complex complex calculation ever done successfully is apparently factoring 29 with a specialized algorithm for 29.

Shor's algorithm has been used to factor 21, not 29. 29 is prime, and people don't usually talk about factoring primes because the factors are trivial. But otherwise, yes.

These are going to be quick and dirty installations in order to power AI data centers for people that bribed trump. It's your taxpayer dollars going to finance AI slop.

Construction isn't expected to start until 2030 at the earliest. From TFA:

Energy Secretary Chris Wright cited “tremendous interest” among developers of data centers that would buy the power, as well as utilities and energy companies. The nuclear plants could begin construction by 2030 and become operational in the mid-2030s, Wright and other officials said Tuesday.

By that time, the AI bubble may have burst, or the grid may have gone even further into renewables, or both.

We need more power, but nuclear isn't the way anymore. I was a supporter of nuclear until around 2020, when I saw how fast solar and wind were gaining. Both have consistently shown enormous growth because they are not as specific in their land requirements, can be installed in small numbers, and the levelized cost of energy (LCOE) for them has plummeted to become profitable even without subsidies. Storage is still a challenge, but we're seeing rapid improvements in that, too, with sodium batteries rapidly catching up in capacity.

TFA says that construction on these won't start until at least 2030, and if they make that, it would be amazingly fast for how reactors are built these days. In that time, wind is expected to expand by almost 50 GW and solar by 40 GW. Battery storage is expected to almost quadruple in that time. By the time the reactors are built, they will be a tiny fraction of the new power generation installed and they will probably be the most expensive part of it.

Government intervention in international currency markets is "capitalism"? Since when, and by what definition? Wikipedia says "Capitalism is an economic system based on the private ownership of the means of production and its use for the purpose of obtaining profit", which on the surface neither implies nor aligns with the Chinese government controlling the CNY-USD exchange rate.

IAI hasn't build a fighter since the Dagger/Nesher that Israel sold to Argentina after the IAF was done with them. They tried to build an F-16 competitor, the Lavi, but stopped when the US refused to allow any funding to be used towards its development.

Israel likely has the technical capability to build a modern fighter. Whether it has the money to do so on its own is an entirely other matter.

People don't pay capital depreciation. It's a bookkeeping technique to reflect that durable capital assets don't last forever. People pay for the assets up front. Capital depreciation decreases the book (=accounting fiction) value of the asset and spreads the tax deduction for the purchase expense over the same time.
