And if a worker were to look at how some code changes just looking at the files modified, he would probably notice that we keep tearing open and modifying the same piece of code many times, he might ask why can't we just fix all the bugs at once.
Streets I imagine would be very different depending on what's underneath.
Yeah, most software is a bit more complex than underground utilities. But the latter are far from the same, and I'd argue it's actually much more difficult to prod, examine and debug what's going on underneath an active roadway than it is to debug a bit of software, for example.
Just spend 20 minutes looking at/reading ladder diagrams, an organizational method electrical control systems. You'll learn that you pretty much 1 for 1 programming logic (that first motor controller you look at is the same as hello world, and algorithmically it's somewhere between 6 and 12 if statements).
