Material design is like the design of a typical hotel room. It aims to accommodate everyone. It aims to be a temporary home for everyone and a permanent home for no-one. Hardly anyone would actively choose to make such a clinical, impersonal, unopinionated environment their home.
That's what happened with user interfaces when software ate the world – once the UI designers tried to reach everyone, be the place for everyone, the hotel room design took over. The call to bring artistic view into designing interfaces only makes sense if you are brave enough or lucky enough to allow your product to be opinionated, to not be for everyone.
As a trained artist in the technology field, actively working on speculative HCI designs, I don't often see companies that are open to opinionated designs. Most expect the designer to produce decoration, whereas the actual strength of a good designer lies in creating a space, a choreography, an interaction that fits the needs of the customer exactly right. That solves the actual, human need in a way that is true to the medium.
don't turn your project into a hotel room, I beg you!
