Did you read the parent? When you simplify "Copy Right" to this phrase, you make me think of a simple world, where I am allowd to copy my bought CD onto a mp3 player and am allowed to do a full disk backup of my Win10 PC. And because I cannot use both copies at the same time ther would be no loss for the seller. The simple copyRight law was meant against people who copied books in order to sell them. This is not about muddy waters, this is about you doing over-simplification.

carbon nanotubes or small silicon slivers could be used as building blocks. Then use scanning tunneling microscope and AFM to assemble them. You my need cryo and vacuum at home. But that is nothing compared to the optics used in mass manufacturing ( cost wise that is ). A robot is similar to a 3d-printer. So pick and place can be done at home. Likewise pick and place at the nm level is basically possible. Carbon nanotubes can be grown at home. Silicon. I mean you must buy the materials. With thin enough Si-wires it might be possible to spot impurities and cut them out.

For me it seems politicians are afraid that their country is to be left behind and thus establish a standard way for people to get a license to let a car drive on a limited number of streets. In this way, autonomous cars can be phased in over the next 50 years. Also what is the problem with city traffic? Parking in the city is part of it, cars can do that autonomously today pretty well. This sonic sensors are mostly for city traffic. Besides parking they are useful to detect pedestrians running in front of the car. And fueling the car was not done by the driver in the past, but by the operator of the gas station. Good 'ol time. In Europe a truck can drive non-stop without refueling. Low speed, Diesel engine, large tank.

The goal of space exploration is to flee from super-novae. Humans become nomads again. Mostly living on space-ship, moving far below c, using fusion energy, communication using radio waves, developing A.I.. It will not allow us to reach outer pulsars, but in the long time will spread us across the galaxy until all stars die. Did not RTFA.

I did not RTFA, but if you use a ball with lots of cameras for all directions and a lot of overlap you know your surrounding completely. Dunno how that "infinite" comes into your mind, I just see 12 films / streams and a modern GPU at work.

And place two documents side by side or see 2 consecutive pages of one document to decide on page break, I mean, do real work. 4k less then 1000 €

Flying cars are great if you drive 200 km/h on the autobahn and suddenly someone cuts you off or behind a corner everything is red. Radar detects obstacle, map knows that there is no bridge or high voltage line => jump. Typically in these cars there is only one person with lightweight cargo. One needs props, lifting body, but no wings. On the car shown in the link I cannot see many compromises. Pusher prop may be not that ideal, but not that bad either. Folding wings are standard on carriers. Aerodynamics and a good suspension are good for road and air.

I do 30mph, but only to catch green light, or when overtaking grandma's on bikes. I like to weave through the oncoming left turning cars. On many roads (without bike-lane) I have the same speed as the cars. Some dumb drivers try to overtake me and then cut me when they have to avoid a parking car on the left side. When I drive by car, I often adjust to the speed of the bikes (if the traffic-light is red anyway). Right turning cars are a nightmare, I like to jump on the road, overtake left and then return to the bike lane. I hate it if the traffic planer build obstacles in between . Of course I live in a city where everybody rides like me or worse: Münster in Germany

For the use case with the mountain and the lake in the way of the car: Why no use a plane? Lots of roads a wide enough for a real plane. I think with self driving cars and mandatory apps for the rest it should allow to dynamically clear roads of cars. The the pilot of the plane pays the drivers of the cars some compensation and: Win-Win. The other use case is traffic jam or an obstacle on the road. For this the cars only need to hop to the next free road. They need not to be efficient.

CRTs do not flicker if they are refreshed after at max 10 ms. There may be a problem with intensity fluctuations. LCD panels do not wash out if they are refreshed after at max 30 ms? Since the desktop runs in 3d today, this is useful for everybody. You could even watch movies at 48 fps, PAL at 50 fps, NTSC at 59.997 fps fullscreen. No more tripple buffer! Maybe we could even get variable timing for horizontal refresh in order to calculate post-processing on the fly like in on the gameboy.

I bought a camera and a notebook. Thus a license for creating and viewing H.264 was forced upon me. I use FLOSS for H.264. I never look back. Wikipedia is for the whole world. People like me having a player license from MPEG-LA does not mean, other have it, too. And I am still not allowed to produce professionally and distribute. Wikimedia is not youtube. I do not like other people watching videos using the money I spend (or may spend). Bandwidth hog. Limit global video bandwidth on Wikipedia. I do not like unformatted data. Limit audio, limit bitmaps and jpegs. SVG is slightly better. See how many articles feature these nice and standardized tables!
