What is the biggest problem that you think humanity will face in the future?

I don't know what category this falls into (if any) so I guess this is a philosophical question in the sense that I want people's opinions on the matter. <br><br>I think one of the biggest problems humanity will face is the advancement in technology and how we deal with the consequences of that advancement. For example, the rise of AI. I think it will be easy to replace human workers with AI which will cause a huge economic shift and the issue of who will own anything. Also, the rise of robots and the issue of if robots should be given human rights.<br><br>What do you guys think?
