Unfortunately, arguments are only entertaining, if both sides represent oversimplified extremes. And so we end up with nonsense either-or discussions all the time.
The really interesting solutions are somewhere in between the extremes, using the puristic arguments from the extremes to distill which of the properties need to be combined for a truly better solution.
Text is too important to leave behind completely. Arranging glyphs in a grid with interactions invented before screens existed is not.
