It really depends if we die and on how our children's children view Bitcoin. It's code, it's an explanation of an voluntary economic system, literally any part of it is subject to change given adequate reason. Never is only useful for physically impossible things, like light going faster than the speed of light. It is possible that code changes, for example, give satoshi's coins to miners as the block reward starts to decline for some security related reason and enough people in a hundred years agree to run the software. I'm not saying it's going to happen, I'm just saying that it's not outside of the realm of being a solution to some problem in a future which has infinite unknown problems.
