For example:
They: "First photo-realistic CGI was the dancing baby GIF."
Me: "Hey, photo-realistic CGI in movies dates back to Jurassic Park (1993) and earlier, even into the 1980s"
They: "No they were animatronic."
Me: "Look it up, lots of scenes 100% CGI."
They: "I googled 15 seconds and found this random video that supports my true fact knowledge that they were mostly animatronic, so you're totally wrong."
(At this point I block people because they're a lost cause.)
