The goal of post-modern society is to create wealth without additional energy costs.

If I write software that schedules health care more efficiently, I've created value and therefore wealth. If I make a video game that's more fun than the previous generation of games, likewise.

Kids glued to "fun" (addictive) video games on their phones is not wealth, it is the feeder channel for these "efficient" health "care" schedulers, in your other example.

That is, IMO, arguable. Entertainment has always been valued by humans. It is just the non-physical equivalent of fancy clothing or jewelry. And clothing/jewelry is most certainly a form of wealth. So, it can be argued that things that you can buy that make you feel better emotionally or increase your social status are forms of wealth.

That some forms of entertainment may be detrimental if abused in the long-term is an orthogonal topic.
