Time, effort, and skill being equal, I would suggest that AI access generally improves the quality of any given output. The issue is that AI use is only externally identifiable when at least one of those inputs is low, which makes it easy to develop poor heuristics.

No one finds AI-assisted prose/code/ideas boring, per se. They find bad prose/code/ideas boring. "AI makes you boring" is this generation's version of complaining about typing or cellular phones. AI is just a tool; it's up to humans how to use it.
