If by that you mean what society and people can use Bitcoin for is infinite then I would agree to some extent as long as it is used for good alone. Afterall it's decentralized and has can be freely used by free people without limit unlike centralized systems.
One of the features that can be used for lots of things is the private keys. You could absolutely use it for lot of things including locking your door and other private properties and truely feel safe because nobody but you knows the keys to unlock them. I have never really like the centralized digital locks.
But if you mean the price going up continously without end, that will also depend on whether it can continue to be useful without end
I believe that the price will continue to go up forever until there is no more bitcoin. People are forgetting that innovation is very important in the world of humanity and I believe that there will be something much better than blockchain one day, it is not going to be today and right now but it is going to happen one day. That means that we are going to end up with something much better in the future but that could take maybe few decades and that means bitcoin will go up constantly during that time.
So, the price could continue to go up forever but it could also crash and be nearly nothing in the future when something much better comes up and that is not about bitcoin, bitcoin could continue to be whatever it is and it all depends on what happens with other stuff. If a new thing comes up then bitcoin goes down, if not then bitcoin keeps going up.
