Oh, come on. Hollywood can tell a compelling story to inspire people to get into fields they wouldn't have considered otherwise, even if only as amateurs and hobbyists. A lot of kids watching Iron Man are probably excited to grow up to get into machine learning and robotics.
They can tell a compelling story but I hate how they distort the reality. I feel like a lot of the plots are altered to fit this Hollywood format. Sometimes the antagonists feel forced. Or the friendships feel forced. Or the back story fells forced. I don't want a movie where they just take someone's name and likelihood and plaster the standard Hollywood tropes on it.
But... people actually do write on windows and glass like that. It happened at the University I worked at, it happens at my current job. It's just a thing.
