This is oft-repeated but it's not as simple as that.
There's no sharp line dividing the two. You already have "VR + passthrough" which is pseudo-AR. And AR turns into VR as soon as you cover up enough of the real world.
There's some experiences/applications that suit AR more than VR and vice-versa. Most devices will offer a mix of the two.
I think a ballpark to aim for is 95% reality, 5% overlay. Whether that's achieved using passthrough or not is a minor detail.
Since the benefits will be pretty subtle QoL things, the form factor has to be very ergonomic to make it worth it, so widespread use could be decades away.
