To drag out the trite comparison once more: not writing assembly will atrophy your skill to write assembly, yet the vast majority of us is perfectly happy handing this work to a compiler. I know, this analogy has issues (deterministic vs stochastic, etc.) but the code remains true: you might lose that particular skill, but it might not matter as you slide on up the abstraction latter.
Not writing assembly may atrophy your ability to read assembly is my point. We still have to reason about the output of these code generators until/if they become bulletproof.
