Are you yourself positively looking forward to this possibility?
Why not? It's just the question whether we are still in this world? In the next 20 years I will be too old and maybe some of us here will be on the same predicament.
Nevertheless, Bitcoin never fail us, I mean when I join in 2017, I never thought that we will someday see 6 digits. And moving forward 7 years, he did break it. So anything can happen in the next 20 years, specially that during that time, almost all Bitcoin has been mined, or at least 20 million has been mine already and so the price will really go up as the last 1 million will be mined around 2140.
