This is a false dichotomy. The truth is we are constantly moving further and further away from the silicon. New developers don't have as much need to understand these details because things just work; some do care because they work at a job where it's required, or because they're inherently interested (a small number).
Over time we will move further away. If the cost of an easily managed solution is low enough, why do the details matter?
