It's labelled as "Experiment" in the titlebar, it says that it has limitations and that feedback will help improve, and it says that it may display inaccurate information. I think that covers it all pretty well.
nice, missed that on the bard site.
> Bard is still an early experiment, and may sometimes provide inaccurate, misleading or false information while presenting it confidently. When it comes to coding, Bard may give you working code that doesn’t produce the expected output, or provide you with code that is not optimal or incomplete. Always double-check Bard’s responses and carefully test and review code for errors, bugs and vulnerabilities before relying on it.
