Sometimes, the cheapest and most efficient LED bulbs are in the blue end of the spectrum, especially when the color temperature doesn't matter too much - like a flashlight.

In that case, it's not so much the color temperature as it is the spectrum. The color temperature tells you what temperature of blackbody radiation your light source most closely resembles, but it doesn't tell you how closely it resembles it. Our eyes work best with light that has a distribution similar to blackbody radiation, i.e. with a wide, smooth distribution of wavelengths. If the distribution has sharp spikes, it can cause things to look the wrong color compared to what they're expected to look like. This is most obvious if you get one of the LED lights that uses a mix of pure red, green, and blue to simulate other colors; you can get something that looks like white if you look directly at the lights, but nothing they shine on looks right. That color shift is what CRI (color rendering index) is supposed to measure.

Lights have to have a CRI of at least 80 to qualify for Energy Star, which means that most household lights are now fairly decent. Cheaper lights and ones not intended for general illumination may go for higher efficiency at the cost of lower CRI, which is what you're probably noticing in the light from flashlights. High CRI (90+) lights are available, but they're usually a bit more expensive and less efficient.

Generally speaking, anything with lots of parts has more points of failures.

Maybe that's true in general, but in the specific case of lighting, incandescent lights obviously have a much shorter life span than CFLs or LEDs. There's plenty of reason to think that incandescent lights do badly with power spikes. My experience is that they're a lot more likely to fail when you turn the light on than any other time, which suggests susceptibility to power surges. It's just that replacing dead incandescent lights is a regular activity, so the occasional failure due to power spikes is much less noticeable than for a light you expect to replace once or twice a decade.

I wouldn't be so sure that energy efficient lights a lot more sensitive to dirty power than incandescent lights. It's just that incandescent lights have such a high background failure rate. If a CFL or LED light dies, you assume there must be a problem with it because their rate of natural death is so low. With incandescent lights, you would have a hard time telling whether one died because of bad power or because it's just given up the ghost.

I find the whole think kind of surprising, since it is known that the whole brain doesn't go to sleep at the same time. Sleepwalking happens when part of it isn't asleep at all.

Sure, just capture them and subject them to brain surgery for the implant, then turn them lose so you can capture them easier next time.

In case you haven't heard, there's a more fun way of getting kids.

Those damb religio-political dogmatists keep blocking publication of my papers on the theory of anturgic phrogneal boropathy.

AI has to get in line behind my flying car.

Your subject line holds the answer: Maybe the idiot futurists really are in danger of being surpassed by machines!

They just haven't figured out that the rest of us aren't idiots too.

People who think AI is a looming threat to humanity learned all they know about AI from comic books and movies.
