Fair enough, but even then it's blame-shifting away from the actual cause of the problems.

I don't think we're going to get physical interfaces back until car manufacturers (or whatever) are forced to because of said cost-cutting.

Most executives don't have the vision or creativity to come up with these trends; they have to pick them up from somewhere. I think there's plenty of blame to go around though.

The trends adapt to the requirements of the customer. See also: the appeaiance desktop interfaces having phone interfaces that don't fit desktop affordances at all.

Note that "customer" can be a manager or similar higher up in the hierarchy.
