Personally, I feel as though I'll accidentally think of the elderly as less human than the young, and forget that they can be open to new things as well. The more I've realized it about myself, the more I feel I begin to see it in others too.

I don't believe I was making the mistake of thinking of people a little older than me as being less human. I have elderly friends that are avid gamers and love thier smartphones, tablets, and Facebook (which I consider to have had mass adoption).

VR headsets I put in the same category as the Microsoft Kinect or the Nintendo Wii. They are kind of fun, impressive technologies, but ultimately they are kind of a pain to use.

This. The inertia it takes to actually use it has to become as low as flipping on the TV and channel surfing. Having to locate a headset, strap it on, etc. is not what people are willing to do. Also, people don't like things on their face.
