I'm only guessing, but I think it was because you seem optimistic about technology. Especially AI.

An increasing percentage of people view optimism, hope, or excitement as childish or worse. Anytime you focus on anything positive they leap from the shadows to dance on your joy. It must feel nice squishing between their miserable toes or something.

Still, I appreciate your enthusiasm and hope to see you build something really cool. The future will be made by the enthusiastic, and if they don't want to come along they can wait in the car. I bet they wear blue jeans to the beach.
