This is something called the metric expansion of space. The metric value is changing at a local level where the measurement is taken. I think it is misleading to talk about space as a dimension moving at some speed, because speed is really distance per unit time. the expansion of space is just space per space changing. We tend to embed our explanations as if the universe expanded from a point on a piece of paper, it doesn't really work that way, the paper in a sense is being generated as it goes along. The speed of light is just some measured velocity value that happens to be pretty close to c when we measure it at various places around the universe, light goes through the metric of space. The metric of space doesn't really say much about what that speed is. So c just goes along the metric as the metric is generated.

I think he would have been better to use the money to set up training programs for skill sets that are useful to society, particularly infrastructure aspects like plumbing, electricians etc. May be use the money to set up in school programs for really specific things like programming, or target specific types of students to figure out what they might excel in.

Imagine a scenario of several factories that are built by robots. The maintenance of the building is handle by robots too. For example an air conditioning unit breaks down, an oil leak etc etc. There is a robot that comes along to deal with it. The computer that controls these functions monitors it all and responds. The factory has its own robot guards, makes its own weapons etc. It needs more iron ore to make parts? It has a copy of all the maps of geological surveys and sends out a robotically controlled truck and excavator to dig up the ore. It gets the ore and brings it to the robot controlled smelting plant and so on. But this is probably not likely for another few hundred years.

This is imagery in the article is really very misleading. What would be more meaningful to set the visible spectrum to black ( so no colour for the buildings) and then set some colours for each individual wifi transmitter. In fact it would look more like an image of Earth from space with only the lights showing, but rather than light it would be a microwave image. It would probably show only the faintest outline of buildings as the RF is absorbed creating an odd looking set of structures. But to 'see' the RF you would also need to set up a kind of 'RF reflective' fog particles in the scene to view the reflections ( a bit like the way you need dust to see a laser beam in the dark)
