Young developers taken seriously?

Hello. So i am currently 18 years and been doing programming for about a year and a half. Recently i moved to a bigger city where i found several programmer meetups. I am a little nervous going to these meetups as i can only see people in the range of 30-50 going to them, and i got a feeling i wont be taken seriously as a developer. What would you think if you saw a young developer (lets say 15-18) enter a meetup/presentation?
