People have the capacity to learn and scanning a QR code once you’ve seen it done once is pretty straightforward. during covid QR code menus replaced physical menus in NY for most restaurants. People complained (i don’t particularly like them either) then adapted.
Different strokes for different folks and all that but I'm a bit of a picky eater and love being able to unambiguously mark what I don't want on my food on the ordering web apps some restaurants use now. On the other hand those places that have the QR code link to nothing but a PDF menu are just annoying.
Those people wouldn't be able to interpret the data anyway. You forget that most people don't have basic competency in science, and basing decisions on that data would be extremely difficult to start with.
