What exactly is the advantage of using Butterknife for Android?

I'm doing the Android Course where we build a Weather app, and we use Butterknife in it. I'm definitely going to use it since Ben says it is way better than not using it. I was just wondering though, if I was to not use Butterknife, what would I have to do differently and why would it be not as cool as using Butterknife?

It's just a convenience thing. ButterKnife only uses one line to populate a View field, whereas normally you'd have to use two. Multiply that by all of your View fields, and it starts to add up!

@BindView(R.id.title) TextView title;

vs

TextView title;
title = (TextView)findViewById(R.id.title); // in onCreate

Okay, I get it now. It really helps me understand things when I can see the exact difference in code that occurs. Amazing, thanks Ben!
