It's this.

And on the compression side, there's a lot of really cool stuff that lets it happen. For example, it dynamically resizes the blocks from 2x2 to 256x256, and they don't even have to be square. It may apply DCT in one, AFAS in another, etc - whatever is most efficient. It uses edge preserving filters to keep the edges of features clean. It can draw in splines and clone regions from one part of an image to another. Where it has to throw away high frequency noise (film grain, noisy textures, etc), it statistically samples the properties of the noise and saves that, and then regenerates equivalent noise. In "busy" areas, like say tree bark or whatnot (where the human eye isn't good at discerning changes), it throws away more precision there, and instead allocates it to details located in fragile flat areas, such as skin and shadows, that the eye is attracted to. It works in default in XYB colour space, based on the actual interactions of the cones in the eye, so it can aggressively quantize things which the brain cannot detect. And in the choice between fast but not-great Huffman coding vs. better but slow and patent-encumbered arithmetic coding, they instead use rANS, which is nearly as fast as Huffman but as efficient as arithmetic coding, and faces no patent challenges. Which is also why you can take a legacy JPEG and rapidly losslessly reincode as JPEG-XL and get a file that's ~20% smaller - you're swapping Huffman for rANS.

(That's the lossy mode - there's also a dedicated lossless mode)

Nope. Communism is a classless form of socialism. Pretty much theoretical for any social group larger than the Dunbar number (welcome to your little tribal village).

Socialism is authoritarian in that a central bureaucracy is responsible for making decisions. No more free market, wisdom of the crowd knowing better than the central government does, or individual rights. It may not be totalitarian and in fact be quite benign. And you can even elect the leaders who will manage your life for you. This is easy, given the "free cheese" model of democracy. Also read the story about the turkeys in The Black Swan.

I agree with that. Completely.

Riders study traffic safety rules, take test, demonstrate proficiency. Get a little card with name and picture to be shown to LE officer following an incident. Too many points and we'll pull it.

Maybe even for bicycles. Thinking hard about pedestrians.

... has a pretty good camera system installed in a few select places. I've seen the video products of the system in my neighborhood. I can only guess at where the cameras are, but it appears as though they are in a few street lights. This may be why we can't upgrade to the newer LED lights in a few block area. Only the old sodium vapor bulb types have enough room in their housing for all the gear.

I could be mistaken and the cameras are in the crows sitting on the lights. Because, as we all know, birds aren't real.

Socialism.

This was a thing during Stalin's day. Each citizen was expected to watch and report on his/her neighbor. Even in the more "enlightened" regimes of the current day, a lot more information about you is public. Like what you earn or what property you "own". Just so public outrage can be harnessed to stop inequalities from arising.
