On the other hand, you can walk over a bridge any amount of times without understanding the nuts and bolts of it. There are plenty of ways to build a bridge, there are static concrete bridges, there are bridges that can open, there are hanging bridges and a lot more variants. But for the people making use of them, the implementation matter a lot less than the purpose - connecting two places. But yes, you are of course right in that if you build bridges, you need to understand the mechanics, and someone that builds a language of course need to have a deeper understanding of how the underlying abstractions work together than most of the users will have.
