That is a definite yes. Are we showing our full potential? That is so definite not all of us. The first thing we have to do if we are going to advance is to stop war, hunger, and poverty. Everyone should be given standard homes and food so that they don't have to worry about these things and they can focus on the sciences.
Your question isn't clear. Survive what? I'm guessing just survive in general.
Everything has its end and eventually we will die out. We might go as far as taking over the solar system, the galaxy, the Universe, and we might even go interuniversal if that is a thing. But eventually die out. Besides maybe the Universe, nothing can last forever.
