X's value had been hovering around the $25bn mark but is suddenly worth $45bn, which doesn't seem to add up?

And, of course, in all-stock combinations it is the ratio between the two companies’ sizes — rather than their absolute values — that is most intriguing. It determines how big a slice of the combined pie each set of shareholders is going to end up with. In this case, xAI’s are getting about 70 per cent, while those in X are getting the remaining 30 per cent.

Whether this is equitable is hard to determine. xAI has very little revenue, but apparently lots of promise.

The two companies have many common shareholders, starting with Musk but including some venture capital investors. Indeed, Musk has given investors who backed his acquisition of Twitter a quarter of xAI’s shares. Should the exchange ratio turn out to be lopsided, at least they will have been on both sides of the deal.

A fusion reactor puts out high energy neutrons, higher energy than fission even. So a fusion power plant is going to be HUGE just from the shielding itself! Sure, fusion is much safer than fission in that you can't have a meltdown and the fuel waste is harmless (though tritium fuel is not). But beyond the fusion core, whatever technology that is, you need lots and lots of shielding, lithium breeding blankets, tritium recovery systems, and a steam turbine loop. And that last part (blankets-breeding/recovery-steam turbine) has never been done with a working fusion reactor.

Plus, fusion just doesn't work at small scales due to confinement issues and power density on the first wall surfaces. It's not like you can scale things down like you can for an enriched fission core in subs or aircraft carriers.

Oh, and did I mention the shielding?

We're better off trying to make hydrogen work for long haul ocean freight. Sure, the energy density isn't all that great, but we have working examples right now.

Look, there's clearly a huge conceptual gap for you here that can't be filled by asking questions on a forum. That said, I'm going to give you another example of how things work these days.

I used to have a stove that, almost to the second that the warranty expired, started throwing error codes about eight hours after we used the oven. Which meant that around 2:00 or 3:00 in the morning it would start beeping until I turned the power to it off and then back on, which is effectively a hard reboot. I looked into it. The two most likely causes of the error code were

1. A faulty temperature sensor in the oven, or
2. A fault with a resistor on the motherboard causing it to misinterpret the signal from the temperature sensor

If it was the temperature sensor that means it was a physics problem that manifested itself as a software error that could be cleared by rebooting.

If it was the motherboard it that means it was a physics problem that manifested itself as a software error that could be cleared by rebooting.

Either way the temporary fix was a reboot.

The longer term fix would be to take the stove almost completely apart, test a few circuits with a multimeter to identify the actual problem, then order a replacement part and wait a week for it to arrive. The motherboard was considered non-serviceable so I'd have to order the entire thing, which cost nearly what the stove cost when new. The temperature sensor was cheaper but still more expensive than I thought it should be. And the hassle of replacing it was higher than the hassle of replacing the motherboard. So I got a new stove.

So there's an example of an issue that may have stemmed from poor engineering, may have stemmed from faulting manufacturing slipping by QA, or may have stemmed from an unforeseen interaction of both of those things. But at any rate, it most likely was a physics problem that could be temporarily bypassed by rebooting my stove. This wouldn't have happened with an old fashioned stove that relied solely on electric circuits instead of electronic processing.

I'll leave it to you to apply my experience to answering your question. But really you should go elsewhere and start learning how the world around you actually works.

Naveed asked me what is my biggest concern? And I said the thrusters and the valves because we'd had failures on the OFT missions. ...So you're just looking at data and engineering judgment to say, 'OK, it must've been FOD,'

Looking more near-term: If we want an interconnected global economy, we need shipping. It is impossible to run a freighter on solar power; there simply isn't enough sunlight hitting one to move it a reasonable number of miles per day even at 100% efficiency. Sails leave you at the mercy of the wind. Oil needs to be phased out. Nobody has the slightest clue how to invent a battery that can put out 50 MW for twenty days straight without recharging. Fission is too expensive, largely because of the engineering and staffing needed to make it not super dangerous. But a 20 to 100 MW fusion reactor, that weighs less than 100 tonnes per megawatt of shaft power, might be just the ticket.

Sceptre makes non-smart TVs, as does ViewSonic if I recall. But if you're looking for Samsung/LG quality panels with zero smart stuff, you're not going to find them, but you can still technically run them without ever connecting them to the internet.

Even if not, it's impressive and has a point...or would have one, possibly, if it were getting more widespread coverage.

Why are the songs not identified or attributed to a composer/artist? While a playlist is playing, you get full music controls, but the visible artwork is generic for the station/playlist you're listening to and contains no track info other than length. So if you hear something you like, you have no ability to go find more of that artist on Apple Music (or wherever).
