Peak UI / UX was some years ago, exactly when depends on any given persons particular preference.

What we have now is akin to a Sheperd tone[1], where the design has to get intentionally worse so that corps. can then go on to boast about how the new design in following years is better than ever, but on the whole no real progress is made.

1. A Shepard tone, named after Roger Shepard, is a sound consisting of a superposition of sine waves separated by octaves. When played with the bass pitch of the tone moving upward or downward, it is referred to as the Shepard scale. This creates the auditory illusion of a tone that seems to continually ascend or descend in pitch, yet which ultimately gets no higher or lower. - https://en.wikipedia.org/wiki/Shepard_tone
