  • You clearly didn’t comprehend what I wrote. Educate yourself on this topic - not from forum arguments, but from TEA and policy papers.

    For one, I said ‘base load’ generation isn’t needed. Your thinking that is is means your thinking on the matter is 10 years out of date. If you insist base load is needed, then gas plants and carbon capture systems are far cheaper and faster to build.

    You don’t care, though, as you aren’t seriously involved in the policy and just want to live in a world where you are right 🤷.


  • Base load is an outdated concept. It is cheaper, by an order of magnitude, to install surplus generation capacity using renewables and build storage to cover periods of reduced production.

    Nuclear reactors actually make terrible ‘base load’ generation anyway, as large swings in output induce thermal cycling stress in their metal components AND the economics of these multi-billion dollar investments depend on running near max output at all times - otherwise the payback time from selling power will extend beyond the useful life of the plant.

    The policy wonks shilling for nuclear are not being honest. The economics for these plants are terrible, they are especially terrible if The Plan ™ is to use nuclear as a transition fuel to be replaced by renewables - as then they won’t even reach break even. To say nothing of the fact that a solar installation in the US takes 6 months, while there have been two reactors under construction in Georgia for a decade…

    50 years ago, nuclear was a great option. Today, it is too expensive, too slow to build, and simply unnecessary with existing storage technologies.

    If y’all were really worried about base load power, you’d be shilling for natural gas peaker plants + carbon capture which has much better economics.

    Instead of looking at the number of closed plants, one should look at the sum of emissions

    That was in the link I posted. Emissions are Currently at record highs.

    Slowing growth isn’t enough; we need significant, sustained, reductions in the very near future, and negative emissions and sequestering carbon in the medium term.

    None of that is happening at a scale that would inspire optimism.

    Building out more and more renewables doesn’t mean anything if emissions aren’t falling - and they aren’t. Since 2021, nearly 4 full years, the world has closed less than 1% of active coal power plants.

    The buildout of renewables has arrived hand-in-hand with an increase in total energy usage. The energy mix has improved greatly in favor of renewables, tons of CO2 per KWh is way down, unfortunately we just use more KWh so total emissions are still rising.

    Everything in the meme is a leading indicator for positive change, which is wonderful, but the actual change needs to materialize on a rather short timetable. Stories about happy first derivatives don’t count for much.


  • It depends on the type of fusion.

    The easiest fusion reaction is deuterium/tritium - two isotopes of hydrogen. The vast majority of the energy of that reaction is released as neutrons, which are very difficult to contain and will irradiate the reactor’s containment vessel. The walls of the reactor will degrade, and will eventually need to be replaced and the originals treated as radioactive waste.

    Lithium/deuterium fusion releases most of its energy in the form of alpha particles - making it much more practical to harness the energy for electrical generation - and releases something like 80% fewer high energy neutrons – much less radioactive waste. As a trade-off, the conditions required to sustain the reaction are even more extreme and difficult to maintain.

    There are many many possible fusion reactions and multiple containment methods - some produce significant radioactive waste and some do not. In terms of energy output, the energy released per reaction event is much higher than in fission, but it is much harder to concentrate reaction events, so overall energy output is much lower until some significant advancement is made on the engineering challenges that have plagued fusion for 70+ years.





  • I see the point you are trying to make, but inflation doesn’t quite when that way.

    Comparing the prices of the same commodities at two different points in time is literally how inflation is calculated, the increase from $1.50 to $4 is real.

    Now, what the inflation-adjusted dollars are telling you is that if eggs had only increased in price commensurate with general inflation, they would have gone from $1.50 to $2. The extra $2 increase is above what a consumer would expect given the general increase in the prices of everything else. If someone (magically) had a salary that increases with inflation, they would find eggs today to be a larger fraction of their spending if they kept the same level of consumption.

    Eggs are more expensive both in absolute and relative to other products. The reasons for this are complex, but due in no small part to people continuing to buy large quantities of eggs even when they were heinously expensive in the early days of the pandemic. The market absorbed that information and came to the conclusion that eggs were previously undervalued.




  • No, not even close.

    I’ve used Unix systems for years at work, and have dual-booted windows with various flavors of Linux at home for just as long. When I just need something to work, particularly something new or after a stressful day at work, I just use windows.

    Why? Because it will just work. Maybe it won’t work precisely how I want it to, maybe it will send all my data to Bill’s push notifications, but it will run. In the rare case it doesn’t, a quick google will fix it.

    Compare that to Linux, where most things will work most of the time. And when they don’t, you get to hunt through GitHub issues off-the-clock like a peasant, wading through comments from people with entirely different configurations and ‘dunno it works for me’.

    Linux is for tinkerers, and for people who want a Unix shell and can’t afford a Mac, it has a long way to go to be more than that.



  • You haven’t really described what you are imagining.

    Proper “AI”. No more coding, you just tell the machine what to do and it will do it. I don’t think in the physical world but computers and every profession that is not physical will be much rarer. Either pivot to AI Management or be the arms that the AI “guides” through a task.

    Telling a computer specifically what to do and how to do it without making mistakes is coding. Programming is a level above that, in designing the architecture of how to approach the business problem.

    What the other commentator is saying, is that simple being able to tell some model ‘build an app that does XYZ’ requires AGI because that set of instructions is not complete - the machine requires outside knowledge and the ability to make judgement calls in order to complete it.

    If that isn’t what you meant, it is at least what you said. The breakdown in communication here, between humans, should also serve as another reminder how difficult it is to convey an idea to another entity and how that problem will remain difficult for a very long time.



  • There is always a tension between security, privacy, and convenience. With how the Internet works, there isn’t really a way - with current technology - of reliably catching content like that without violating everyone’s privacy.

    Of course, there is also a lack of trust here (and there should be given the leaks about mass surveillance) that the ‘stop child porn powers’ would only be used for that and not simply used for whatever the powers that be wish to do with them.

    The world bank isn’t involved so much in printing money - that’s central banks like the US Federal Reserve or European Central Bank.

    They do love to force developing nations to adopt US-style capitalism by withholding loans for needed development projects. They also focus far too much on increasing GDP at all costs and do not give really any weight to increasing living standards or reducing inequality. Basically, think loans to institute Reaganomics and you won’t be too far off.

    The loans pay for large capital projects (power plants, large-scale irrigation, etc) that are built by the state and then mandated to he handed over to private entities that then charge rents and extract wealth. Not every loan and program is bad, but there’s plenty to give pause when they are involved in a project.
