That is an understatement. I just searched (not asked) "planet with orbital period two days", and it answered first "there is none in the solar system", even when I uses "-solar" "-sun" -Venus" and so on no useful result.
Only when I entered "I am not talking about the solar system or venus, you idiot" into the AI chat it offered extrasolar planets. Four candidates with "two days" orbit. A google search check, with results from science.nasa.gov revealed: Only one of those four is correct. Last sentence I wrote into the AI chat was: "Kepler-407b is wrong. HAT-P-23b is wrong. WASP-43b is wrong. TOI-2267 d is the only right answer. You suck."
The google-AI is even too stupid to google-check its own results.
