What looks modern is very often a cycle between "because we have the technology to do it" and "because we have the technology to not do it anymore".

We arrived at a point where putting more shadows, glitter, transparency effects and particles is no longer hard, so it no longer looks modern. The only solution to go forward is to remove all that fluff in a statement saying: "Our tech is so good we don't even need to show it anymore".

The same applies to building materials in design. 40 Years ago, concrete was all the craze and the material of the future. We would use that shit on everything. Today, a building made only of concrete looks passé, but I'm sure it will come back with a vengeance once we find out how to make it lighter/color-changing/glow-in-the-dark or something stupid like this.
