This isn't about coal emissions or clean anything. It's about killing the coal industry before the cryptocurrency industry can buy in to make their own electricity.

Bit late for that now, innit?

But... Apple charge a lot to spec a machine with > 8GiB, and it's not user upgradable afterwards.

I do appreciate that it makes sense for them from a business perspective, but previously Apple products, whilst expensive, have generally been over-specified, and thus continue to be usable for many years after purchase. 8GiB is a bit tight though... if they charged less for the entry level, non-upgradable machine... then perhaps that's useful, but otherwise, it seems unwise to buy the low-end hardware because it's still expensive!

I just did my taxes with TurboTax - had tried TaxSlayer which has more free/cheap offerings (I use it for my mom-in-law's taxes) but didn't have the payment option I was looking for. Not only does TurboTax keep trying to upsell, it also keeps asking for permission to share my data with world+dog. And if I revisit a section (income or whatever) it asks the same upsell questions again that it asked the first time I went into that section.

I have kids. I don't need anyone else to beg me repeatedly for things.

168,032 vs 168,395 seems pretty close... if US tech industry headcount in 2023 was the same as it was in 2001. Which it wasn't. A Deloitte report from 2021 indicates the industry grew from ~3.6 million workers in 2001 to ~5m+ in 2021. So the 2023 layoffs affected a smaller percentage of the workforce.

Of course, that ~40% overall growth in industry headcount pales in comparison to the growth seen by MFAANG - 4x for Microsoft, 15x for Apple, 40x for Netflix, 50x for Meta (just since 2009), 600x for Google, and 2000x for Amazon.

Fusion had "a chance" for quite some time. But this result here is based on simulation and theory and basically an educated guess, not much more.

if the tech being talked about is ReBCO high-temperature superconducting tape, and the person talking about it is from MIT? They're well beyond simulation and theory. They built a full-scale magnet back in 2021 and generated a 20 Tesla field - and kept it at that strength for over 5 hours.

However, in recent decades - well after the start of ITER (and thus not employed in its design) - there was a massive change on the scene: the commercial bulk availability of room temperature superconducting films. These allow for magnets with double the field strength, which basically lets you scale down the size of a commercially viable reactor by an order of magnitude. And not only that, but they offer a whole host of other advantages, including easier / cheaper cooling, easier ability to open up the reactor to get inside to replace the liner, and so forth.

It's a complete game changer for the industry. That doesn't mean "viable nuclear power overnight". Heck, it doesn't even prove economic viability at all - you can't predict that really well in advance. But what it does mean is that, yes, at a reasonable scale, we can build productive electricity-genereating fusion reactors. This isn't some exotic, "This One Weird Trick Lets You Make A Great Fusion Reactor" thing - this is well established, well researched physics here. Just with better magnets. And those better magnets makes a *huge* difference.

You meant to say "high-temperature" superconducting, not "room temperature" -- we're still talking 100 Kelvin, give or take. But being able to use cheap, easily-produced liquid nitrogen for cooling rather than liquid helium is a big deal, yes.
