I think this is right overall. Making an AR headset requires serious compute and power and there’s no way that will fit in a contact lens anytime soon. This demo is a HUD, which is much easier and already solved by glasses. So I think this tech is way early for practical use-cases. On the other hand, AR glasses have some challenges of their own. Allowing the user to see through the lens and focus their eyes on the world around them while seamlessly displaying on top of it is a major engineering challenge which is mostly unsolved. Setting the distance between the display and the eye to zero and locking the display to the eye position makes this easier in several ways. It would solve the field of view issue. I just don’t see how you pull it off without having your eye connected to a puck by a fiber optic cable. I think you need several generations of improvements in semiconductor and display tech to fit everything in the contact lens, even if it’s just a wireless receiver and display for an image that’s rendered somewhere else. But it’s good that there’s people working on it to push the tech on the right direction.

assuming a wireless way of transmitting to the contact lens i'm not sure the value of putting all the compute in the lens vs having it external like say your mobile phone. it's like bluetooth headphones, but for your monitor instead...

  You still need a great deal of processing for the signal and image stabilization/readings from the sensors. This test version gets away with the M0 for that (well, as much as one can say that looking at the lens) because it only has ~61k of on/off pixels to make a HUD, which also doesn't need to be refreshed often just restabilized locally. Typical AR headsets get away with not having to deal with stabilizing eye movements, more place to stuff processing anyways, and no concern on being able to receive massive bandwidth video streams for more lively content.
