Bitcoin already reaches its goal by making a peer to peer network usinh blockchain technology. But I believe that it will not stop eventhough it is already complete. It will not stop to make some innovations and resolve all problems regarding with transaction, charges and security. Unless, if Satoshi Nakamoto will die or he don't want to change anything from bitcoin but I am sure that lightning networks come from his idea.
I think mass acceptance and adoption must be made to make these things possible for bitcoin. Because the main reason for having bitcoin for now is to have a decent form of investment and to deal with trading platforms where the possible goal of bitcoin is to be an eye universal money in the form of cryptocurreny that can support transaction systems for the future and become a stable investment method for people who can be used in trading.
