The whole asking Bard thing towards the end is completely meaningless and I'd argue irresponsible. They even say<p><pre><code> But of course, the observation that Bard consistently makes these claims can’t be seen as evidence one way or the other
</code></pre>
and then go on to quote a bunch of stuff Bard said.<p>If I had to speculate, sounds like it could have used anonymized gmail data (could they have some kind of pii removal tool that they run first, that's common, though I wouldn't trust it too much), or something is being pretrained on gmail and fine tuned on something else (hard to see a reason for that). Anyway, google is acting suspicious, but pretending the chatbot's "opinion" has any bearing is disingenuous.
