By the same (virtually nonexistent) logic, neither are games in general, or operating systems, or computers, or anything that is not strictly "necessary" for one to survive. Yet all of these things clearly have a strong intrinsic value to society, else we wouldn't be working so hard on all of it. If you don't enjoy VR, don't use it; it doesn't get much simpler than that. I can guarantee you that no one on the SteamVR dev team is going to care about your opinion or where you think their resources are better spent. Want to change that? Apply for a job at Valve. Pointless comments aren't going to do anything.
