AR is the future, and will be much bigger than VR, but it is also a much harder problem to solve.

I know companies that are very interested in professional VR applications today using the Vive, but Hololens isn't practical yet. I think in a few more revs it will be really great. VR now, AR when it's ready, but AR will definitely be bigger.

I feel the same way. In Sam Altman's most recent interview he talked about hours of use per day being an important metric for a new product.

It seems like the first high-use product in this category will be a lightweight regular looking set of glasses that simply displays your notifications.

Then in the future, add a camera to display overlays on the real world.

Same here. I'm much more excited about AR devices like the Hololens and Google Glass than VR devices like the Rift or Vive, because AR has much farther reaching applications than just gaming.

In our current tech landscape, we mostly interact with the digital world through screens. AR has the potential to turn any real world object into a human-computer interface. I definitely think AR technology is going to be nothing short of revolutionary once it matures, possibly even more so than the advent of the modern smartphone.

And we already have super successful AR apps like Snapchat and Pokémon GO
