I doubt it, now by this I do not mean there will never be a new technology that could surpass bitcoin, after all bitcoin itself was created when no one expected for such a development to happen, so this could happen again, what I mean by this is that in the case it happened, such a coin will not be a cryptocurrency but something else, basically it will have to be a new technology based on different principles than the ones bitcoin uses, if this is not the case then the bitcoin developers will just implement those advanced features on bitcoin and we could forget about that coin ever replacing bitcoin.
