Actually useful is subjective. What's the carbon footprint of all the gpu rigs in the world used to play video games? Is that useful for you?

It's not subjective. At least not in the way you are wording it. Bitcoins algorithm has no purpose. It's burning power to mine a resource that has no inherent value.

Gaming has obvious value. Entertainment in all forms is necessary for people to feel happy.
