Comment Source term for Einstein's field equation (Score 1) 42

in his actual papers on relativity mass does not "create gravitation." Energy, momentum and some off-diagonal terms like stress and pressure gravitate. There is no mass term in the stress-energy tensor

There most certainly is. Density-- mass per unit volume-- is the (0,0) term of the stress-energy tensor.

Comment Re:All for it, but would like to know the launch r (Score 1) 14

If the launch fails at a point where it is say 50 miles up, and the reactor has been turned on prior to launch.

The conops says that the reactor doesn't get turned on until after it's successfully placed in a high orbit.

A good feature of nuclear reactors is that they aren't dangerously radioactive until after you turn them on.

Based on the cost of products from China vs the price of products made in China but sold by non-Chinese companies, I'd say the price well more than covers the cost of everything for practically any product where they also choose to display ads.

They just want more, more, always more.

Dude, are you living under a rock?

These bands are creating new music. But the money that allows them to do so comes from their old music. I have bands in my collection that have been making music for 30 years.

And I'm pretty sure even small bands make good money nowadays from touring,

No they don't. They don't even make ok money. Tours are expensive and a lot of people, from road crew to venue security, take their cut before the musicians. The big guys, they make a killing on tours. But the small ones sometimes don't even break even.

In fact, a common wisdom in the industry is that touring is worth it not because the tour itself makes profits, but because it builds a fanbase and drives what is called "catalog discovery" - both old and new fans looking buying the albums with the songs they liked (and for the old fans, didn't know).

This study: https://www.giarts.org/article... says that 28% of income across all the musicians surveyed comes from tours. The share is larger for the rock/pop sector where it nears 40% but even that isn't easy money. And if you consider that only 20% of the rock/pop musicians make more than $50,000 a year, then it becomes a hollow statement.

Plus, it goes directly against your first statement - while on tour the band is not creating new music. So if you want to drive musicians more towards constantly creating (which most of them already do), then you can't make live performances the main income source.

Here's a case of a very experienced journalist getting caught by including made-up quotes that had been hallucinated by the AI he'd used to summarize research information: https://www.theguardian.com/te...

Vandermeersch added: “It is particularly painful that I made precisely the mistake I have repeatedly warned colleagues about: these language models are so good that they produce irresistible quotes you are tempted to use as an author. Of course, I should have verified them. The necessary ‘human oversight’, which I consistently advocate, fell short.”

When even experienced journalists fail to find AI hallucinations, you really can't expect unpaid volunteers to do better.

There is more than one study and more than one way to look at it. Especially for streaming, having a catalog matters, especially for the smaller artists who will never have a charts-level hit:

"In 2024, nearly 1,500 artists generated over $1 million in royalties from Spotify aloneâ"likely translating to over $4 million across all recorded revenue sources. What's remarkable is that 80% of these million-dollar earners didn't have a single song reach the Spotify Global Daily Top 50 chart. This reveals a fundamental shift from hit-driven success to sustainable catalog-based income, where consistent engagement from devoted audiences matters more than viral moments or radio dominance."

Also don't forget that many studies such as DiCola's "Money from Music" focus on the superstars and the big hits. That is true, the charts pop music generates 80% or so of its income within the few weeks it stays in the charts and then drops of sharply.

Honestly, I don't care about the charts and superstars. They wouldn't starve if we cut copyright terms to six weeks. I do care about the indie artists that I enjoy. Who after ten years get the band back together for another tour through clubs with 200 or 500 people capacity. I'm fairly sure they would suffer if the revenue from those albums disappeared. And disappear it would. Maybe fans would still buy the CDs from the merch booth, but Spotify would certainly not pay them if it didn't have to.

Wikipedia is choosing to die. There is a lot wrong with a lot of what people are doing with GenAI but it is also super useful.

Unfortunately, even the best LLMs sometimes make up information ("hallucinate"), and the stuff they make up is deliberately crafted to appear exactly like real information. This is simply unacceptable for an encyclopedia.

If Wikipedia were written by paid professionals, you could plausibly put in place protocols to check and verify, and fire the ones who fail to check properly, but even paid professionals have been seen to let hallucinations through. As it is, as an encyclopedia that it is put together by volunteers, forbidding AI is pretty much a forced choice.
