I agree with the transformation part, and almost said one big transistor or computer but don’t think either are right either. I still think switch is closest.

Computers turn electricity mostly into a display (monitor) (I’m not calling out heat cause every computer does that) The data piped out of data centers almost purely specifically routed packets - so that looks more like a switch to me
