I'd say a lot of software is comparable in complexity to the large bridges that exist. Of course there are massive software projects that dwarf any bridge ever build. But a lot of software is only moderately complex. I don't know about infrastructure in the US. I don't live there. I'm happy with the infrastructure in west Europe though. I wish that much care was put in to the software I use every day.
