Gamers are people who spend time
It's not just "spend time", "gamer" also implies a certain amount of obsession. "Casual gamer" covers the gamut, but just "gamer" is between Casual and Hardcore. I would bet that most people, who others consider to be gamers, would also add that just spending time does not make one a gamer, but also the amount of zealously one has while playing their games.
I see no good reason for this separate infrastructure to connect to the Internet.
Let me know how your IT can remote in from home without having an Internet connection at some point. Remoting in is nearly a requirement of all information systems.
What, exactly, was the long-term benefit of NASA 'space exploration' in the 1960s?
Cell phones, microwave ovens, satellites, computers, huge leaps in aeroengineering. The list goes on. NASA has single handily spurned nearly all technology that we currently use. Prior to NASA, there was almost no demand for the research required for our current tech.
All tech started as a "Waste of money". An amusing physical phenomena with no practical application until it became reliable and cheap enough for an engineer to make something useful with it.
As a beautiful picture of a distant galaxy shown to a hungry child is not going to help that child when he's hungry, instead he needs food on the table, so that's how you make decisions on how to prioritize and spend money when the money is tight.
Money represents time and our current society has excess beyond belief. Anything that someone does that isn't farming is excess time. Money is not an issue. You want to talk about feeding the poor? It's not a money issue. The poor don't need to be fed by others, they need be educated and given a safe and healthy environment. Sending them food actually create more problems than it solves. Corruption forms around the influx of food donations and exacerbates issues.
What people once thought to be wasted money in tech that no one will ever use is now the backbone of EVERYTHING.
In our current point in history, we have a lot of excess time. We should be spending it exploring new tech and getting off this fleeting planet. It won't be habitable forever. We're due for another mass extinction, we best get moving, not getting chained down worrying about starving children in civil war torn areas.
With your bare hands?!?
