The Real Problem
There is a real, useful progression happening in QA tooling: from AI helping write a test, to AI helping fix a broken test, to AI (in narrower cases) deciding what to test and when. Each step hands the agent more decision-making authority and less human review per decision. That progression is where the actual risk lives, and it is almost never discussed honestly in vendor content, because vendor content is selling the progression, not warning about it.
"Autonomous QA" as a term is used inconsistently across the industry (Industry consensus): some vendors mean "agent-assisted test generation with human approval gates," others mean "agent runs the suite and files its own tickets," and a smaller number mean something closer to "agent modifies test scope and expectations without a human in the loop for each change." These are not the same risk profile, and treating them as one continuum, the way most vendor marketing does, hides exactly the point where a team should slow down.
