From Akin's Laws of Spacecraft Design:

A bad design with a good presentation is doomed eventually. A good design with a bad presentation is doomed immediately.

Presentation will always be important as long as humans are involved because we're biologically wired to be attracted to good-looking things. Now I do think that what we associate with "good" will violently change, as it always does (look at fashion).

My guess is that verbosity will be an immediate turnoff, em dashes another immediate turnoff, and we'll value ooga booga conciseness over all other aesthetics. We've already unknowingly begun to move in that direction with the minimalism trend.
