To my surprise, this shows that Moore's observation is still intact. https://www.karlrupp.net/2018/02/42-years-of-microprocessor-trend-data/ Alas, the most recent advances in transistor count are achieved by making bigger chips, not denser chips, and single thread performance is becoming stagnant.
We're unlikely to see linear feature size halved in a production process in the next 5 years, so an honestly named 3 nm process isn't likely soon. We'll never see a 0.1 nm process, because 0.1 nm is smaller than an atom.
There are fewer than 10,000 firearm homicides in the U.S. annually.
A person's most fundamental right is the ownership of his own life. Inherent in that is the right to do with his life whatever he wishes, so long as it does not violate someone else's rights. The ownership of your own life implies the right to end your own life. Objecting to that, as you seem to be doing, is naked evil.
We are already at the point where speed-of-light delays have a significant effect in limiting clock speed. An improvement of even 10X in clock speed may be something that we'll never see, not in silicon, not in carbon, not in fairy dust.
Surely there's a place for you at the Daily Worker or MSNBC. Well, no, the Daily Worker folded in 1958. Its leftist pseudojournalism was as obsolete then as yours is now.
What's the incremental cost? The prices you cite are far too high, and the paperback price exceeds the retail price of most paperbacks. Remember, retailers typically buy at 40% off list price, which includes publisher's profit and expenses, author's cut and his agent's, etc..
There are 2 theoretical approaches that would allow higher efficiencies for incandescents. The first is the use of a material that is not a black body radiator, a material that radiates well in the visual band but not in IR. The likelihood is that no such material exists that is usable at high temperatures. The second is reflecting IR back to the filament, so that a high filament temperature can be maintained with less electrical input. Such lights have been made, but the gain in efficiency isn't much because filaments are small so it's difficult to aim a substantial portion of the IR back at the filament.
The best LEDs are already converting more than 50% of electrical energy to visible light. Incandescents run about 5%, and I don't think they're going to catch up in 50 years or ever.
The great improvement in optics available to consumers in the last decade or so has been made possible by nano-coating, which substantially reduces reflections. Reduced reflections means more elements can be used, so more aberrations can be corrected. Sigma has been leading the industry with new high quality designs.
The down side of these super lenses for a full frame camera is that they're heavy, many of them over a kg.
Generally, it's not true that thermal cycling is what kills incandescent lights, just ask a manufacturer. The necessary high temperature of operation causes tungsten atoms to be ejected. Either through randomness or manufacturing irregularities one part of the filament becomes narrower than the rest; that place becomes hotter and atoms are ejected faster in a positive feedback manner until it melts or is too weak to hold together.
There were, and maybe still are, 7-segment displays using filaments for the segments. In some applications a segment might cycle on and off every second. If thermal cycling were the dominant failure mode for incandescents, those displays would have had unacceptably short lifespans.
High frequency audio under water can be easily beamed, and dissipates fairly rapidly with distance. A submarine 200 feet down beams ultrasound at the surface, the ripples from which are detected by an airplane overhead. An enemy attempting to listen ten miles away may be 40 dB down in the beam pattern, 30 dB down from the ratio of distances, and 60 dB down from attenuation through the water (numbers hypothetical). Total 130 dB down, maybe undetectable.
The Life Extension Foundation does sell supplements, and occasionally they are too enthusiastic. However, they are at the high end of the ethics scale for the supplement industry. They fund research, and the articles in their magazine cite many high quality references. They also encourage the use of some things they don't sell, a prime example being the prescription drug Metformin.
The LEF is a good organization, and their claims deserve to be taken seriously.
WalMart sells 250 capsules of 5000 IU (at the high end of modern recommendations) for $7.88. That's 3.2 cents per pill. Some places sell at higher prices because they can; some shoppers aren't doing due diligence and don't care.
It's astonishing that there are still people who believe there is a Social Security Trust Fund, or that such a Trust Fund could exist. All SS receipts go into the General Fund, all SS expenditures come from the General Fund, and all claims to the contrary are accounting tricks, smoke and mirrors.
When Social Security "runs out of money," retirees will be paid from the General Fund. If that doesn't happen, there is no place on Earth that the Senators and Representatives can hide to escape the wrath of the retirees.
Your understanding of technology, and even everyday life, is sorely lacking. Do you know the difference between open-cell and closed-cell foam? Paint is more likely to crack and flake off than "have bubbled up and melted off".
With regard to the Tesla in space, so what? Nobody claimed it was going to be driveable, or even pretty. It was just a publicity stunt, and almost everybody knows it.
We can also do without plumbing, central heating, electricity, paved roads, refrigeration, telephones, and computers. Why would we want to? Those things all make life better.
For example, Los Angeles has hundreds of bus routes, yet few places have buses that run more often than once every 20 minutes, and some places it's every 2 hours and not on Sundays. Would you want to wait 20 minutes before you can go someplace, and another 20 if you have to make a transfer? Repeat that for the return trip? Even while not waiting a bus goes half the speed of normal traffic because it has to let passengers on and off. Time is money, and time is life.
Cars make life better, and for most Americans car ownership and use is a rational choice.
There is very little money to be made in a healthy population.
This is just an obscured example of the Broken Window Fallacy. Healthy people spend money on many things, some of which will actually advance technology, many of which actually make lives better.

Here's how to tell if the government is wasting money. If there's something called the "Bureau of Ocean Energy Management", it's wasting money.

Profit in the wide sense means that you gain from your actions. If you profit on nothing, you die -- soon.
