No, they're actually the same thing: making an honest assessment of reality. In the first case you're doing so to prevent self-delusion. In the second you're doing so to prevent others from clouding your judgment.

Before this, everybody in the industry thought GPS solved the aerial navigation problem.

Many people in industry believed this but no one with a brain ever did. The vulnerability of GPS has been cause for concern for a long time, and the decimation of the VOR network has always had a lot of people up in arms.

I'm well aware of the law. I was a full-time flight instructor for years, and the relevant regulation is the first one I taught when introducing students to the regs.

But I'm not talking about whether the captain has final responsibility and authority for the operation of the aircraft.

I'm talking about whether it's sane to escalate directly from something that is very much not an explicit threat of violence, to involving people whose primary tools are suspension of physical liberty and acts of violence.

(Also, please note: that rule says two things. The captain has final authority, yes, but they are also responsible for the choices they make. It's not a free pass to do anything they want for any reason.)

Actually, I don't think it's a good idea to bring your politics into a an enclosed pace like this where people are forced to be a captive audience, notwithstanding that I agree with theparticular sentiment expressed.

That is a very, very, very different statement than "I'm calling the FBI."

You're talking about should or shouldn't. The issue here is past that point: whether it's then right to involve people who are empowered to take away your physical liberty, and worse.

TNT equivalent is defined as 4.2 MJ/kg.

It isn't this simple for liquid oxygen and methane mixtures, and there's a great deal of disagreement between industry and regulators over what the right percentage of TNT equivalence is. Naturally, industry thinks the percentage is low, and regulators are skeptical, so there's a government-run test campaign going on as we speak to collect data for proper modeling.

Whenever a new way is found to improve efficiency, choices have to be made about how to distribute the new surplus.

Choices are made by people who have power and imposed upon people who don't.

The people with power under current systems don't care about the people who do the work. They care about getting rich. So if there's an efficiency gain to be had, all of that new efficiency is going to be put towards increasing output or reallocating work. None of it - under current power structures - will ever go towards allowing workers to work less, because workers aren't the ones deciding where it will go.

Dawkins doesn't know what consciousness is. He doesn't know what it is because nobody knows what it is. We can't measure it. We can't even detect it, except in onesself. Any claim, by anyone, that someone or something other than themselves is conscious is based entirely on inference or faith.

I'm using the terms consciousness and conscious in the "hard problem" sense here.

Drones are already regulated. You aren't allowed to fly higher than 400' AGL without ATC authorization, an altitude chosen because it has special significance in the National Airspace System. Nor are you allowed to fly in the vicinity of an airport without authorization.

This particular restriction we're talking about was completely unjustifiable. But the regs exist, and they aren't just made up nonsense. They're the result of systems engineering and a real risk management process.

The need for belonging is also really powerful, and companies actively try to fulfill that need. Not, generally speaking, for nefarious purposes, but because people do better work when they feel a sense of belonging.

If you decide that your work is against your values, you're also deciding to separate yourself from the group, even if you don't actually leave the company. That's painful. It's not an excuse, but it is a powerful motivator.

Something I've observed as someone who works in the physical sciences and used to work as a software engineer is:

Very few software engineers understand that tolerances are fundamental.

In the physical sciences, strict equality - of actual quantities, not variables in equations - is almost never a thing. Even though an equation might show that two theoretical quantities are exactly equal, the practical fact is that every quantity begins life as a measurement, and measurements have inherent uncertainty.

Even in design work, nothing is exact. It's simply not possible. A resistor's value is subject to manufacturing tolerances, will vary with temperature, and can drift as it ages. A mechanical part will also have manufacturing tolerance, and changes size and shape with temperature, applied forces, and wear. So even if a spec sheet states an exact number, the heading or notes will tell you that this is a nominal value under specific conditions. (Those conditions are also impossible to achieve and maintain exactly for all the same reasons.)

Even the voltages that represent 0 and 1 inside a computer aren't exact. Digital parts like CPUs, GPUs, RAM, etc. specify low and high thresholds, under or over which a voltage is considered a 0 or 1.

Floating-point numbers have uses outside the physical sciences, so there's no one-size-fits-all approach to using them correctly. But if you are writing code that deals with physical quantities, making equality comparisons is almost always going to be wrong even if floating-point numbers had infinite precision and no rounding error. Physical quantities simply can't be used that way.

I hope Adobe dies and becomes a warning to others - sorry, a "case study" - that is taken seriously. I adored Photoshop, starting with version 3, and watched in horror as Adobe stripped itself for parts. The damage is done, but hopefully we can still get some good out of this if it makes other companies realize that abandoning your users is a death sentence.

Airlines and aircraft manufacturers are already heavily incentivized to be fuel efficient. It's the most expensive part of a flight. (Sometimes crew salaries are more expensive but not by much.)

Because rationing isn't step one. Putting out a warning that rationing will be necessary if things don't change is step one.

Rationing causes serious problems. A warning in advance gives people and powers time to turn things around before rationing becomes necessary.
