I disagree, the biggest barrier to commercialization of this technology is that it's technically infeasible. For the projection to make it through your pupil onto the retina your eye needs to be carefully aligned with the projection beam. This just barely works indoors when you pupil is hugely dilated, now imagine being outside when your pupil is contracted. It's a non-starter.
