I expect somewhere in the AI harness there's a branch that effectively mandates "You must always answer."
Which results in it grasping at Reddit comment straws.
And which, in typically modern Google fashion, nobody there gives a shit about fixing, because the PR made their top-level AI KPI go brr.
Google is increasingly proof that you can't run an effective scaled tech company without a Gates or Jobs who occasionally uses the fucking product themselves and descends with fiery vengeance on whatever team drifted too far from user alignment.
