While I learned assembly language and machine code and a tiny bit of electrical engineering in school over 20 years ago, and I think it was helpful to have a basic understanding of how computers work at that level... I don't remember the details, and certainly haven't had to use them in my career as a programmer, and you don't really need to understand this stuff to be a solid programmer. Computers are devices for abstracting, always have been. If we had to understand everything down to do anything, we'd still be at the punchcard stage of computing, and not doing anything more sophisticated than was done then.
