So, the Steam Deck has already been a tremendous success and will absolutely certainly make Valve far more money than the index ever will. 

That's real bad news right? Is the index about to go the way of the Steam controller, the Steam link, Steam boxes, SteamOS and literally every other thing valve have ever tried? 
There's no way they'll continue to pour money into the VR hole if the Deck is such a ridiculous success as it looks like it is going to be.
