The vast majority of fabric would be made in large swatches by loom and shuttle (manual). Then it'd be cut to size and shape, and the seams would be stitched by hand. That's the only part that'd involve needle and thread. And it'd still be done by people in the 3rd world for pennies an hour, so the retail price would be pretty much the same.
Completely depends on what's being farmed. Livestock need tending daily if not more often. Grain needs to be milled or sold to a miller. Cotton needs seeds removed, corn needs chaff removed, et cetera. And then you can go to market every day/weekend to sell your stuff. Some crops only have one planting season, others have two or three, and crop rotation can lead to planting and harvesting several times per year. Pesticide/water/herbicide can be applied. Research can be done on weather/new equipment/new seeds etc. However, there were surely some subsistence farmers who did one crop once a year, left irrigation to the rain, ignored weeds and pests, and threw the product in the cellar whole to eat when needed (potatoes?).
You're lacking a sense of the scale of time. Once we're immortal and regularly going on million-year space expeditions, then it'll be more plausible. 8 months is nothing. We'll have pulsars sending out coded messages to uncontacted aliens to check out the local space diner long before entropy dissolves everything.
a solar panel that converts sunlight directly into hydrogen using moisture in the air
I didn't realize hydrogen was made out of sunlight. Perhaps the writer meant "converts moisture in the air directly into hydrogen using sunlight"? Although I still wonder what happens to that oxygen, I guess it goes poof, or transmutes into hydrogen.
The neat thing about relativity is that even at relativistic speeds, your laser's photons will still travel at the speed of light relative to you. So it'd still work. Assuming it worked at all, and your end-point was near a different black hole of similar size, the delta-V/s decelerating should be the same as it was accelerating.
Adding what form of energy? If it's adding kinetic energy, that means increasing the mass or speed of the photons. If adding more wave energy, that means increasing the amplitude of the wave, right? How would gravitational slingshot be able to increase mass or amplitude?
If this actually worked well, wouldn't we see halos around plenty of black holes, since other space-faring civilizations would be using the technique? Presumably enough laser light would be scattered by gravitational lensing or turbulence or whatever to be visible from here.
Let me get this straight. Photons would be fired toward the periphery of a black hole, so that they'd slingshot around and come back... faster than light? What?
My phone's camera is normally pointed at the ceiling with me far out of its FOV. A horizontally-facing camera (particularly in my bedroom) is more concerning, particularly if the camera is inconspicuous.
If the plebeians are able to pull themselves out of the genetic gutter, then who are the bourgeois going to systematically oppress? They won't want their children to have more mate competition at the genetic high-end, either.
I'm curious how the debate will shake out on whether these gene-edited girls should be allowed to reproduce. That debate WILL happen by the time they reach child-bearing age. IIRC it was a germ-line change.
I think the 'quick refueling' thing is oversold. If you don't have to stand there and watch it, most people won't care how long it takes. If you're on the road, so long as you're recharged enough in the time it takes to make a pit stop, to make it to the next one, then that's good enough.
More likely, they'll just buy out an EV manufacturer or a battery production company. Toshiba's market cap is 1/3 of Toyota's cash on hand (~$58B), for example, if they wanted the entire company.
I use an EV to tow a Prius. When the EV runs out of juice, I ditch it at the side of the road and drive the Prius the rest of the way. Hey, works for rockets!/s
Dictators tend to feel anxious that their close officials, or the evil group du jour, are going to betray/usurp them; this is the typical cause of purges. Now scale this up to a dictatorial government, that is afraid much LARGER groups (say, all the Maoists) are going to roll out the guillotines, and the oppression gets much larger in scope and time scale.
Oppression is a side-effect of the #1 bureaucracy goal: continuity of the bureaucracy. Anything that threatens the CCP is considered an "existential threat" by them. The typical way to defeat these things is to have them implode due to power vacuum, although Thailand probably has a better model of having a non-violent coup every 20 years or so.
What the 1660 boils down to is ~15% more performance than a 1060 for the same price. Same amount of VRAM, also. Get your act together, AMD, we're heading toward Intel-style 7% gains per GPU generation.
"in 85 percent of the cases, the two-qubit quantum computer returned back into the initial state,"... According to the authors, these errors are due to imperfections in the actual quantum computer.
Maybe the amazing headline result is due to one of these errors, rather than the null hypothesis being due to errors?

You'd be putting tape over part of the screen, occluding whatever's displayed there (and preventing you from touching whatever is there.)
The phone phreaks that stole documents from AT&T to make their own boxes, were the real early hackers.

Seriously, they'd use the standard "just one drop" test.

So it's ok to gene edit fetuses or zygotes?

Also sunk cost fallacy, in regards to hydrogen fuel cells.

A camera hidden behind the screen? Will they call it the Samsung Telescreen?
You can't even put tape over it. Do not want.
