The mini is pretty cheap but unfortunately doesn't have google cast.

The pro is still an excellent value as it has way better DACs than the google cast and a lot more format support. But yes, on an absolute cost perspective it's not as cheap as the old chrome cast audios were.

But there's still nothing available at this level of quality and features at this price , most comparible stuff is 2-3x the price.

The WiiM devices support google cast and many other protocols.

Did you read the article? Standard traffic cameras or sensors are all you need to implement this. And yes, most places have the technology already in place to do most of it. You just need to add the part to network them and control the lights.

China already "solved" it with the one child policy. They will have the most massive population decline ever in the coming decades. It will probably destroy their economy.

I would be happy for sensors at traffic lights that detect whether cars are there or not. I don't consider that to be meaningful surveillance.

Then we can enslave humanity with the AI slave

This is exactly why I dropped out of college for computer science when I got my first IT job. 30 years later and I haven't regretted it yet.
