I hear you on the worry, I have the same (and probably so do most devs even).

But IMO the endless churning of code will slow down, if it has not already. Quantity does not equal quality as we know, it even erodes it. There are already consulting companies that are "vibe-code fixers".

I am also not sure it's about "elegant" code. What we might call elegant has multiple measurable axii f.ex. well-isolated effectful code layer so you can easily static-code-check it, domains and enforcement of boundaries between them, bespoke linting to enforce business processes and standing code discipline, and many others.
