There’s for sure legitimacy to the concern over the quality of output of LLMs and the maintainability of that code, not to mention the long term impact on next generation of devs coming in and losing their grasp on the fundamentals.
At the same time, the direction of software by and large seems to me to be going in the direction of fast fashion. Fast, cheap, replaceable, questionable quality.
Not all software can tolerate this, as I mentioned in another comment, flight control software, the software controlling your nuclear power plant, but the majority of the software in the world is far more trivial and its consumers (and producers) more tolerant of flaws.
I don’t think of seniors as purely irrationally fixated on the artisanal aspect, I also think they are rationally, subconsciously or not, fearful of the implications for their career as the bottom falls out of this industry.
I could be wrong though! Maybe high quality software will continue to be what the industry strives for and high paying jobs to fix the flawed vibe coded slop will proliferate, but I’m more pessimistic than to think that.
