The video mentions both the GPS and speedometer as potential targets for this technology. Giving it some thought and being close to the age where I might benefit from this, it isn't such a bad idea after all.
(Although I'm short-sighted, so the arguments above don't apply to me anyway.)
Essentially, I'm getting close to doing the opposite of what most people do with reading glasses. For now, I do most minor reading tasks and my work with my glasses on, but for lengthy reading I take them off. Over time, I'm sure, I'll end up taking them off (or looking below my glasses) for almost every reading task, and eventually for work as well.
In the end, though, I don't think the technology will be likely to really solve the issue for me, except to correct a few displays for my corrected vision. I have to pin most of my hopes, at the moment, on improvements in surgery and eventually being able to afford the surgery.
