This seems really misjudged and irresponsible when everyone is trying to push the message, "Trust expert scientists in their field".

"Except when they're joking, but you don't know enough about their field to tell if they're joking, so you just have to hope" is not a helpful message.

Whatever his goal actually was, it could have been achieved without damaging trust in scientists.

If it were Bill Nye or Neil Degrasse Tyson I might agree with you but I think the context is important: this is a French tweet.

Does the Francosphere have the same issues with trusting science that the Anglosphere has?

while I agree with you, this seems like obvious humor, and actually pretty funny. I push back on the idea that we have to be humorless evermore.
