Oh boy, they weren’t fuzzy. Some film outclass the clarity and sharpness of modern OLED, even when it was for B category low budget movies, just that most people watched a 4 week old piece of film in bumfuck middle of nowhere cinema. With a scratched up and badly calibrated focus lens and dirty and deteriorated film over a dirty screen.

Anyways, the biggest problem that physical media solves is not the number of pixels, but the bitrate. Tons of information, specially about color, is lost to streaming compression. Pixel density equation means that the quality of what you see is rarely distinguishable between 1080p, 2k and 4k, depending on how far away you sit from the screen and how big it is. For the typical seating accommodation at home and commercial theaters, you won’t notice a significant change within FHD and UHD. However, you can definitely tell the difference between the 10Mbps 4k (down to as little as 2Mbps if your connection sucks) that you get from Netflix¹ and the steady 32Mbps that Blu-ray can give you.

¹: BTW, it doesn’t matter how fast your internet connection is, the data transferred can get to you at as high speed as you want, but the bitrate of the video file inside the container that the streaming services give you is usually hard capped rather low anyway.

The proponent is a rather successful and rational investor. This was satire, meant to evoke the idea that, if AI was all that the con men are selling, it would collapse the economy. It is not and everyone knows it, but the point is to highlight the idiocy and try to wake up people to the absurdity. I see it akin to what “a modest proposal” was. To nudge the most radical AI ideologues into understanding the dead economy and ghost GDP concepts. If the economy becomes detached from human reality, it will crumble and collapse.

It is just voice messages automated. That’s all. You push to talk, it records your voice message, then sends it to everyone in the channel (group chat). Everyone gets a notification and the message automatically plays on their end. It creates the semblance of radio comms, but everything is recorded and kept in a group chat history. It also depends on service data coverage, since it is just an internet app and that’s all. Basic features like dispatcher mode, diffusion and complex multi-channel setups are paid under a premium subscription. They sell some hardware that interoperates with the app in a radio like fashion as well, but it is all third party, so quality varies a lot. Also, I’m not aware anyone has ever done a security audit on them, the thing is entirely proprietary and closed source, it tracks location as well, so I wouldn’t necessarily trust it.
