If it's something a single senior staff member can do, then - personally - I'd consider it not complex, it's relatively trivial: it can be done by literally a single person.
I'm pro AI, I'm not saying it's not valuable for trivial things. But that's a distinct discussion to the trivial nature of many LLM examples/demos in relation to genuinely complex computer systems.
Doing for < $10 and under an hour what could be done in a few weeks by $10K+ worth of senior staff time is pretty valuable.
