Why does Bitcoin need to surpass Fiat? I don't think it is needed and it is a bit hard to happen. I am not sure if we can manage finance without Fiat at all. In my opinion, Bitcoin is an option to support the world's economy and financial sector. It makes sense as Fiat has some weaknesses nowadays. People need transparency and fast transaction world wide. Bitcoin offers the solution, even it doesn't need the third party and can be sent at any time.
