There's a working group of cryptographers who are spending some of their time researching Bitcoin (and other cryptocurrencies) in an attempt to reduce their value to zero.

Cite?

I find that extremely unlikely. The cryptography behind BTC is very simple and very robust. Oh, it's certainly the case that if someone were to break any of the cryptographic elements they'd have made a name for themselves that would result in them being showered with opportunities in both academia and industry, but (a) that's extraordinarily unlikely and (b) the primary benefit of doing that work wouldn't be related in any way to BTC. Oh, and it would also take down lots of other important uses of cryptography, like TLS. That doesn't make it not worth doing. The fact that it would break so much other stuff is what makes it worth doing.

Where I differ is refusing to associate cost/price with value.

"Value" is too variable and subjective to be a global concept. The only useful way to define "value" is "What a given person or entity will pay". Your gamr-boi puts a very high value on a game. I would value the game at very close to zero. Probably not actually zero... if you offered me a big bundle of games for a penny, I'd buy them because a there's some tiny possibility that I might want to play one or two of them sometime in the future. Especially if the purchase is digital (e.g. Steam) so I don't actually have to store them anywhere. Another person might place the value somewhere between the gamr-boi's "lots" and my "almost nothing".

And "price" is just the aggregate combination of all the potential buyers' values, matched against suppliers' offerings. So price is inherently and inextricably associated with value. Specifically, the value that everyone puts on a good defines the shape of the demand curve, and the price is where the demand curve meets the supply curve.

Your video game example is not a great one, because non-rivalrous goods (my having the game doesn't preclude you from also having it, unlike, say, socks, where my possession of a particular pair of socks means you can't have them) introduce some complications into this analysis. It's much easier to understand the relationship between value and price with traditional physical goods first.

There are two curves, a supply curve and a demand curve. Where they cross is the price. This is extremely simplified :P

In general: the price is as high as the seller can get away with. "Supply and Demand" as "basic economics" only works in niche cases.

Where the curves cross is the highest profit the seller can get away with. This is precisely how the curves are defined.

When talking about supply and demand, people commonly misunderstand that both curves are fundamentally about price, not availability or desirability. The supply curve is "How much is available at each price level". The demand curve is "How much will be bought at each price level". At prices above or below the intersection point, sellers are failing to maximize their profit.

It's profit-maximization that pushes prices to the supply/demand intersection point.

Note that monopoly or monopsony don't invalidate the supply/demand curves, they just alter them. Even with a perfect monopoly, the supply and demand curves still exist; at different price levels the monopolist can obtain more or less to sell, and at different price levels the buyers will purchase more or less. Supply and demand curves don't work or not work in different market conditions. Supply and demand curves always hold, non-competitive market conditions just shift the curves. Even government price setting doesn't change this fundamental reality... it makes price ranges legally inaccessible, which just alters the curve shapes by adding legal risk to the "price".

Supply/demand curves aren't a prediction, they're an observation, and the basic concept is near-tautological.

And they could be up to date for many, many, many years if Linux was installed on those, instead.

Well, if by "many, many, many" you mean "about five". Red Hat provides longer support terms, but not for free.

And then after those years shift from a "update" path to an "upgrade" path and have many years more.

True, sort of. Assuming the upgrade works, which it often does... but not always.

I'm no Windows fanboy, in fact the last version of Windows I used was Windows 2000. I switched to Linux completely by mid-2001 and I've never looked back. But it's really not as rosy as you paint it. The commercial OSes (Windows and OS X) actually do a much better job of delivering long-term support and (in the case of OS X) upgrades. I don't personally care about that for my machines, because I have no problem managing them, and even debugging the occasional update or upgrade failure. But I'm actually glad most of my relatives use Windows, because I would not enjoy having to help them do the same.

You seem to have completely missed the point, which is that what Biden *should* have done -- while his party held both houses -- is changed the law, rather than issuing an order that broke the law. Trump has been far, far worse about this, but it's clear that part of Trump's goal (or the goal of someone with his ear, since I'm not sure he is capable of making and pursuing goals over longer time periods than a few days) is to establish that the president doesn't need Congress.

My voltage doesn't vary much at all no matter how much power I'm pushing. And, unfortunately, I couldn't set my inverters to derate if I wanted. I'm fighting with the installer over access to configure/manager my inverters. They offer quite a good repair/service warranty and also a production guarantee, and won't give me control without voiding both of those so I'm debating which I care about most.

(I somehow replied to myself instead of you. What am I, some sort of /. n00b?)

I agree carbon capture and sequestration is important but I haven't seen anything that looks good at scale yet.

And there won't be unless we motivate research into it.

When there is a decent solution it would be ideal at times of surplus generation when power is otherwise unable to be used

Indeed! This is an ideal use for overprovisioned capacity.

At the small scale I have an issue where in summer my solar surplus is more that my rural grid connection can handle so when my hot water is heated and the house and car are charged I end up with the solar inverters derating

Wow. I generate way more than I use in the summer, but my (also rural) grid connection can absolutely take it just fine. I have 200A service with a 150A breaker (so, about 37 kW), but my generation peaks at about 20 kW. My bigger problem is that if I try to charge my house batteries (20 kW) and my car (12kW) and run my AC (4 kW) and the steam generator (9 kW) and run basic house loads (2 kW) and run my welder (10 kW) that's 57 kW or about 235A. In practice I don't ever do all of those things at the same time (and rarely charge batteries from the grid), so I've never actually tripped the main breaker, but I could do it easily if I tried. I imagine it will happen someday. I could swap the breaker, but the wiring from the main panel isn't big enough to have the proper safety margin at 200A. Running new wiring would be... a big project, likely involving tearing up and replacing a big chunk of my driveway. So, 150A will have to do.

I have not found a good use for such surplus power yet, but carbon capture would be ideal.

Me neither. I ran the math on doing some BTC mining (I think BTC is a scourge on the planet, but I'm happy to take money) but it didn't pencil out. Free power is great for mining, but the cost of the rigs is high enough that you really need to keep them humming 24x7, and I don't have enough battery capacity for that.

Just because we can't magically address all causes of CO2 and pollution in general doesn't we should blindly ignore the issue.

Indeed. We should also, however, recognize that emissions reductions can never get us to net-negative CO2 and that is where we need to get. We should be investing heavily in research into carbon capture and sequestration, because it is the ultimate long-term solution to greenhouse gas emissions, the thing that will allow us to actually reverse global warming.

In the meantime, as you say, we should start by looking at the CO2 emissions sources that allow us to most quickly and cheaply reduce our emissions. The easiest area is electricity production... made even easier by the fact that wind and solar are the cheapest technologies we have for producing electricity, in many cases even when the cost of battery storage is included. And of course as we convert electricity production to non-emitting sources, we should electrify as much as we can the other areas where we burn fossil fuels.

But we also need to be investing in carbon recapture, because some things are going to be hard to convert and, as I pointed out, only recapture can get us to net-negative. We should also be researching geoengineering techniques, such as methods of reducing insolation. Geoengineering isn't a solution (e.g. reducing insolation does nothing to fix ocean acidification), but it may be a necessary short-term measure, and we should be prepared, having already done what we can to understand it in case we need it, and before we need it.

Carbon reduction is good, but it's insufficient and I worry that we're not putting enough into other approaches. A large part of the reason is that people are afraid that attention on anything other than carbon reduction will harm the emissions reduction efforts. That's not a ridiculous concern, but it demonstrates a lack of understanding of the scale and scope of the problem.

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.
