It did not turn out fine. Fortunately no one took it seriously, and at least seniors still have an intuitive model of how the hardware works in their head. You don't have to "see" the whole assembly language when writing high level code, just know enough about how it goes at lower levels that you don't shoot yourself in the foot.

When that's missing, due to lack of knowledge or perhaps time constraints, you end up on accidentally quadratic or they name a CVE after you.
