That's an unfair assessment of tech as fashion right now. Personally, I think the Apple Watch looks ugly, but things like headphones (over-ear and Apple's prominent white in-ear) have been prominent and very popular, especially as a social/status signal. A lot of design work goes into technology.

I think we will continue to see successful tech follow that prominent path, but also the hidden one you suggest. Google Glass done right, hearing-enhancements that are barely visible, slim AR/VR goggles that are more like glasses, etc.

We won't see prominent tech/fashion fade away.
