Having had the experience of having my own performance car stolen temporarily, and damaging it to the extent of needing a new engine and reupholstering, at the time I felt capital punishment is not enough.

You may think this is a little severe, but people who are into cars feel they have had part of their soul ripped out of them if it is stolen and trashed, especially if it is their personal hobby and they are doing it at the limits of their budget.

I understand that many people attach a lot of their self-image to their vehicles, and devote disproportionate time, attention, and money to them. That doesn't mean that their priorities should be encoded into law.

Your hobby is not more important to society in general than human life. Yes, it may be more important to you than some other person's life. Laws exist partly to mediate between people's conflicting self-interest.

What's a "program" ("anything")?

A deterministic sequence of instructions that could be converted to work on a universal Turing machine. I don;t htink this is really a valid criticism.

That's a reasonable definition, although I'm sure there are those who would quibble over non-deterministic operations and such. But "The new program—it could be an idea, a novel, a piece of music, anything—" seems to imply something very different. The paper talks a lot about writing stories, designing letterforms and so forth. Stories are not "programs" in the sense you (and perhaps I) think.

In theory, I suppose, double liability would motivate everyone involved in design, construction, and operation to make sure that there are no mistakes. In practice, every human -- and every human organization -- has the power to cause accidents that they can't possibly pay for. Doubling the liability for those accidents won't make a bit of difference.

I drive carefully. I've still had a couple of accidents, though. If one of those accidents had sent me into a van hauling $10M worth of Swarovski crystal sculptures, I'd have been sorry, really I would, but I wouldn't be paying off the damages. If the courts found me at fault and fined me $20M, I wouldn't be any sorrier, or in any better position to pay.

I wish the author had elaborated a bit on this. I know that we're far away from the "ideal gas" regime here, and that things get independently wonky when you're dealing with supersonic flow, but "cooling down as it gets compressed" is so counter-intuitive that they should throw us at least a few lines of explanation.

Anybody here want to step up to the plate?

Any effort to emulate or restore declarative memory will obviously include emulating the association and activation networks that drive it. Believe it or not, the people doing this kind of research already realize that.

Nobody is talking about adding a USB port so you can plug a thumb drive into your hippocampus and instantly "know" everything contained on it. That would be great, but there's a lot of other work to do first, as you say.

Yeah, but there could be quite a difference between breaking the windshield and breaking one or two of the potentially dozens of cameras that could be distributed around the airframe. It's a lot easier to design in redundant cameras than redundant cockpits.

Well, to be fair (and since nearly everybody else is piling onto the obvious drawbacks), this should actually remove some complexity and a significant point of failure. Windows, their joints with the fuselage material, and the resulting corners are a major engineering headache.

Also, it avoids the whole "lasers into the cockpit windows" issue. </snark>
