To the original point: "crutches" are not a feature, they are a device. They are not universally useful - the same way that prescription glasses are not. A low refresh display may help some people: it is not helpful in general; some people find featureless text editors less distracting, normalcy greets happily the availability of features and options and hides the GUI with a keyboard shortcut.

To your statement: I do not see how «modern devices», on literal terms, can be the issue: they are *organizers* (meant to optimize your time). If people use them differently, that is not a fault in the device.

To your statement again: focus and attention are skills that individuals develop. If they are underdeveloped, they should if sough be developed. If your point is elsewhere, please make it explicit. I must presume you do not think that it is the responsibility of your sofa to sculpt your abdominals (nor, for that matter, to make you use your sofa wisely).
