Does it make sense to believe that Bitcoin could one day be replaced by another cryptocurrency, that is, a cryptocurrency that really does make Bitcoin obsolete?
I don't think so. Maybe there are chances that another cryptocurrency will take over bitcoin when it comes to value but replacing bitcoin? It's too far from possible. Some may say that there is but if we can all see how bitcoin changed the world, bitcoin is original and cannot be replicated nor replaced. Bitcoin has a lot of unique features and it will take more than forever for a cryptocurreny to copy all of it to dominate bitcoin.

Holders and miners should be able to participate in the new digital currency, so bitcoin is still likely to be replaced
