By that logic, a country can't make long-term investments, and can't provide unprofitable services that have other benefits. My two questions challenged your circular reasoning.

The framing comes from this reasoning: not enough resources yet to build 100% renewable generation + storage => still need nuclear or fossils for now But many people think this way instead: we have the technology for all the parts =>

I'm saying there's no storage solution yet. Even combining all storage types, you'd still run out of materials (battery) or locations (hydro) before finishing. It's not speed vs speed. It's speed vs forecasted capac

People often don't realize that intermittent renewables must be paired with backup generation or storage. But energy storage at the scale of a 100% renewable system is currently an unsolved problem. So you really only have two options:

Thank you for pointing this out. I think most people assume that companies are just being greedy when they solder previously socketed parts, for example. I'm not saying it's never a factor. But it also solves real engineering prob

You cover a lot of interesting topics. Some exposition: Reporting power is easy with the power triangle. It's a mathematically exact concept. Measuring power is a different story. Distortions of the assumed perfect sine wave create mea

I don't have a down button, but I can see why someone used theirs. 1. Why would you verify local need, if the need is national? 2. Why would you verify inability to pay with ability to pay? Spain's demographic problems are exacerb

There are actually three parts of the power triangle: real (W), reactive (VAR), and the hypotenuse apparent (VA) power. If voltage and current are exactly in-phase, VA=W and VAR=0. All of the power is doing work. Being out-of-phase is like

This is the difference between a business and a service. The unprofitable lines could have continued as a government-backed service to promote economic development, for example.

Here's a real and recent news article about how potential risks and opportunities are being explored regarding electric vehicles and the grid [1]. It basically says they're looking into stuff and working on it. Neither doom and gl

Seems like you didn't need fixed point in the first place. It's for when you need guarantees.

Both processor hardware and the Linux operating system are powerful in large part because they're opportunistic. But that's the opposite of predictable, which is what defines hard real-time.

We already have carrots and sticks to ensure reliability. That's what regulation is for. Changing those is a lot easier than changing companies.

I've worked for one of the big three you mentioned. Probably a different one, or at least a different group, since the culture seemed fine to me. I can't think of single a time where old code or tools were a barrier to innovation.

An "interconnect" here means the connections between components on a circuit board.

I used to feel this frustration until I accepted that the economics of software usually lead to different requirements. People are making rational choices, so no amount of attitude or culture change will make a significant difference. Diffe

I agree with the general sentiment, but the article explains that this "breakthrough" is a product prototype that meets a government spec. It's hyperbolic wording, but they're trying to warm people up to the idea of even

Yup. The "missions" are an excuse for funding. But the funding is insufficient and misallocated to support the stated missions in earnest. If NASA gets to the moon again, it'll be on a cheap ride they buy from SpaceX.

This sort of already happened when some of the Apollo engineers came out of retirement for the Constellation Program. The program was cancelled and they went back into retirement. Nobody came back for the Space Launch System because it was

I can agree that it ceased being the Roman Empire per se, but I don't see it as being that much different from the end of the Roman Kingdom or the Roman Republic. It's still a continuation.

Ok, so the safety argument doesn't even matter, so why debate it as a proxy for what you really mean?

You're still misusing the term out of spec. Everything else you said is uncontroversial.
