Some people have real jobs that require them to use the internet. I know your mommy is really proud of you for getting that job at McDonald's, but some people are a little bit more capable than that...
You get that automatically if you have home directory encryption enabled, which both Ubuntu and OSX support out of the box in the install process. Then it doesn't matter what is stored on your disk in plaintext because it all gets automatically encrypted and decrypted when you log out.
Richard Wiseman did a study that suggested that "lucky" people were really just positive-thinking people who paid more attention to their surroundings. So while you say "Few people will ever be lucky enough to find themselves in similarly favourable circumstances", it's likely more that "Few people will ever be lucky enough to find themselves in similarly favourable circumstances, and take advantage of them."
Everything I've read by someone who seems to know what he's doing says that writing down passwords is a good idea for most people, and I tend to agree. Writing down passwords and keeping them safe, say in your wallet, gives you a backup in case you forget and lets you be less afraid to pick a long, tough password for fear of forgetting.
By your logic the doctor should not be held liable for not using a generally accepted safety standard. At a certain point when a safety system because so universally acknowledged as basic, it becomes criminal to not include it. That is why we have seat belts. It is why we have air bags.
Two issues with your conclusion. One, the patented technology in this case is far from standard, currently only found on a few high-end saws. Two, the difference between the two cases is in this case the victim knowingly chose not to spend extra on himself, while in your case the doctor, who was supposed to be caring for the victim, knowingly chose not to spend extra on the victim. In both cases, the person who should be held responsible is the person who chose not to spend the extra money. In your case, it was the doctor. In this case, it was the victim.

Wash shirt every other day. Problem solved. And if it's a uniform, wearing the same thing twice a week is expected.
The pipe dream here is solar space power. It's an absurd concept that will never be profitable compared to Earth-based utilities.
I wouldn't say that. It may be a concept that will never be profitable in our lifetimes, but I'd hesitate to say it will never be profitable. When we've already colonized the moon, Venus, and Mars, our power needs very well may exceed the ability of the planets to support, and that's when we move to a Class II civilization. Of course, since we are far from even a Class I civilization, you are definitely correct that attempting to use the sun to provide us with our power needs is a pipe dream at this time.
