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.
Put another way, if you don't know what correct is before you start working then no tradeoff exists.
This goes out the window the first time you get real users, though. Hyrum's Law bites people all the time.
"What sorts of things can you build if you don't have long-term sneaky contracts and dependencies" is a really interesting question and has a HUGE pool of answers that used to be not worth the effort. But it's largely a different pool of software than the ones people get paid for today.
Not really. Many users are happy for their software to change if it's a genuine improvement. Some users aren't, but you can always fire them.
Certainly there's a scale beyond which this becomes untenable, but it's far higher than "the first time you get real users".
