I never get these things. Moving parts wear and complexity multiplies failure scenarios. We are constantly as a society moving away from complexity and moving parts. Less parts, less moving ones, less complexity equals greater reliability.
A good analogy
Apart from when it comes to this fad. Lets add more moving parts because innovation in the area is dead so the only way to look impressive is to add complexity again. Leads the naive astray and for what? More trash going to landfill.
Worth noting if you look at the skyline of the average city where these things are designed to see what dystopian hell holes full of design faux pas and gaudy lurid abominations the cultural design aesthetic promotes. (Vegas is one but that's a containment area for such crimes). Some reflection required on critical thinking and aesthetics if these things are even considerable.
