I just had an experience with a auto soap dispenser, sink, towels and dryer set in the same place in a public restroom, didn’t have to walk to a shared dryer
Plus if electric cars become the norm, the streets will be quiet for the first time since the industrial revolution
The sound of hooves on cobblestone is incredibly loud and annoying!
What really baffles me is modern computers. The whole assortment from mainframe batteries, desktop PCs, laptops to smartphones, watches, wireless earbuds, microcontrollers, miniaturised sensors, etc. Even the cheapest modern microcontrollers have insanely complex and tiny patterning that really speaks volumes for the amount of process control and precision in semiconductor fabs. Truly, I would call the modern IC a miracle if I wouldn’t know better. It is physics, materials science and chemistry at their best.
