It's not inevitable for the masses until the only way to do it is a headset. It will be only a tech for specialized markets and in controlled environments. Gamers, engineers, doctors. You're not going to do AR/VR while walking or when killing some time waiting at the restaurant. One reason is that not many people will carry a cumbersome headset with them. A phone is a better device for those scenarios.

Glasses or contact lenses could change that. I can't wear contact lenses anymore but I wear glasses all the time. Light glasses, not heavy ones.
