It’s your choice, no one will force you to attend events like that but if you think the event really worth going, then you can attend it. But to be honest with you It’s really good when you attend events like that, it gives room to learn new things, you can’t know everything on your own,  it’s better you go out and meet new people so that you can learn from them, you can even meet people and you guys will share ideas, you might be thinking you know almost everything but don’t be surprised when you attend events like this then you will know their are lots of things you still have to know about.
