> Kinetic energy goes as v^2. 2x speed is a 4x car crash. An extra 10 mph is worse at 60 mph than at 30 mph. (40^2-30^2 vs 70^2-60^2). Same 10 mph change, but 2x increased pain.
This should be taught in school.
There's very little cross-disciplinary teaching in schools, each subject is taught separate. But I'm sure a lot of teenagers would drive more carefully if they got a grasp of the concept that whatever your velocity is, if you hit another car, the energy on your body is velocity^2
Yeah. The sciences and engineering and peoples' lives are this richly and tightly interwoven tapestry... and we make almost no effort to teach it. :/
It's hard to find hope for the near term. XR might contribute some market disruption, perhaps permitting better content to slip in. But the default seems "the usual wretchedness, now in XR!" Further, the bottleneck is as much science side as education side, and there's little recognition or effort to address that. On the other hand, when researchers have an opportunity to directly contribute to creating good XR science content, it can be a challenge to get them to leave. ;) So transformative improvement seems perhaps possible, but the effort would have an odd shape, and I've not seen much work in that direction. One upbeat story might be that the bulk of education in China is so very bad, that if something good is ever created, that large delta might energize rapid mass deployment. Maybe. Sigh.
