There is an essential mistake to your approach, yes. But that makes your position a valid one towards the haters here, nonetheless.
“Minimalism” is actually the attempt to DELETE the device and take you to your final end. “Maximalism” (or whatever other way of doing it) is an attempt to highlight the device, and create an experience in itself.
I think your claim is that our “thing fetish”, or “gadget porn” days are over. Yes, they are. We are less attached to things and discourses — that is, discourses that tell us what these things mean to us, abstractly, like part of “our identity”, social class etc.
We have grown more attached to what things actually do, not how they look like. By many definitions (Umberto Eco’s, for instance), that’s good taste — we focus on meaning, not on stimulation only.
