Even vibe coding was coined as term applying to extremely experienced engineers (the guy who coined the term) using llms to rapidly experiment with refactoring and prototyping as if doing pair programming. The negative connotations we now have are an interesting semantic shift.
I completely forgot about prompt engineers. I remember now startups offering insane salaries to them a few years ago. IMO the next iteration will be planning engineers since the new thing seems to be the plan/execution split of these vibe coding tools.
Last year it was "prompt engineer", or was that 2 years ago already. Things move fast on the frontier...
