I can’t imagine any other example where people voluntarily move for a black box approach.
Imagine taking a picture on autoshot mode and refusing to look at it. If the client doesn’t like it because it’s too bright, tweak the settings and shoot again, but never look at the output.
What is the logic here? Because if you can read code, I can’t imagine poking the result with black box testing being faster.
Are these people just handing off the review process to others? Are they unable to read code and hiding it? Why would you handicap yourself this way?
Early resistance to high-level (i.e. compiled) languages came from assembly programmers who couldn’t imagine that the compiler could generate code that was just as performant as their hand-crafted product. For a while they were right, but improved compiler design and the relentless performance increases in hardware made it so that even an extra 10-20% boost you might get from perfectly hand-crafted assembly was almost never worth the developer time.
There is an obvious parallel here, but it’s not quite the same. The high-level language is effectively a formal spec for the abstract machine which is faithfully translated by the (hopefully bug-free) compiler. Natural language is not a formal spec for anything, and LLM-based agents are not formally verifiable software. So the tradeoffs involved are not only about developer time vs. performance, but also correctness.
Vibe coding is closer to compiling your code, throwing the source away and asking a friend to give you source that is pretty close to the one you wrote.
