When quantum computers come out new blockchain tech will follow including bitcoins replacement.
Technology is upgrading, so is Bitcoin in my opinion. Bitcoin developers are getting ready for this said doom of Bitcoin trying to make bitcoin resistant to quantum computers. but of course along the way there is always a competition on who is the number one cryptocurrency, and I also believe that when bitcoin fail, there will be a new currency that wil take its place.
