Having see what terminal vibecoding looks like (to the point where customers say "fix your app" during renewal conversations), I don't think this is likely to happen. There is definitely selection pressure being applied to SaaS companies and I would not expect people not directly responsible (PMs, sales, etc.) to be willing to accept responsibility for technical outcomes; after all they are product, not software experts.

It is possible this leads to a decrease in salary (and positions) but I do not believe the social commentary will pan out in the manner the author proposes. The people who most argue for vibe coding will themselves never accept responsibility for the technical outcomes.
