Nobody will be afraid to use AI.

Use vibration to measure small masses. Measuring natural frequency can be very accurate and sensitive.

It is pollution and it harms people. So in order to do things that are good we must harm others first (or after)?

How dare you stand in the way of regular people burning hundreds of kilograms of fossil fuel in order to spend a couple days at the beach? /s

Not if we follow strict operating procedures, Gordon.

Legit question: if I replicate a patent for a personal non profit use, is this infringement? Perhaps it is because I'm benefiting from the intelectual property.

Depends on how much power you need (speed times force, acceleration and deceleration...) and how much stiffness you need (can't bend?).

Also depends on how much travel you need. It is easier to get 50 micron accuracy over a total length of 100 micron compared to a total length of 1 meter.

Is this related to lasers behaving as as a body with negative temperature when they manage to heat something to a hotter temperature by radiation?

Microwave heating is not a fourth form of heat transfer as it name implies: microwave radiation. Yes, the heat is not being radiated by a thermal source of microwaves, but it is radiation being absorbed. Hence radiation is the mechanism.

Rotational momentum is also heat as it is kinect energy related to movement, linear or not.

If you dig deep enough all our land is on a floating basis.

Enriching uranium is more expensive than making plutonium by a long shot. Modern nukes are two point implosion, not really fiddly. And when was the last criticality incident related to phase transition? Can't remember one.

How so? Huge flooding in Brazil this year, they are not recovering any time soon. Poor countries lack the resources that rich countries literally burn for their luxury.

Because the market is made up of selfish human beings. First they don't care for long term environmental consequences. If that is not enough, then they use fossil because their enemies are using, and not using it means getting destroyed today.

I recall Marvin Minsky saying that 1 GigaFlops would suffice for doing most of what humans do. Current AI is addiction to more data, more compute but no smarts. At least they gave us cheap compute, soon the right people will figure out how to produce real AI, not this travesty.
