I increasingly subscribe to the thesis that many designers and design teams design primarily in an effort to impress other designers. They don't have to use the things. They often don't even really care if the things work at all. They care that other designers - their artistic peers - are impressed.
This does not generally result in what we the customers or users would regard as good design. The phenomenon reminds me of software engineers I've worked with who were more interested in building something with event sourcing and stream processing and functional languages rather than solving the problem more readily.
