99.99% of programmers will never need a machine level understanding of the programming language and architecture they use. Really the only people I see might be machine level understand are 3D engine developers and high speed stock traders. VERY few other people need to understand how you need to organize your collections so that they are brought over in the correct page size from the L3 to L2 cache. From what I have seen many programmers have no clue as to when to optimize something. They want to optimize everything which is a huge waste of time. As for programming classes, they are pointless in modern society but most(ALL?) companies still like to see that you have jumped through the hoops correctly. And that you can be trained correctly to "Be a good team member".
