So I find myself constantly musing the paths forward...
We could follow a rational, predictable (in hindsight) curve that just keeps grinding away, and when you zoom out just looks like a smooth ramp up. The fact that the higher we go (especially from a logarithmic basis) the more it takes to move us supports this. It has the fact that the patient will be rewarded, and there can be many dead bodies along the way of people "glad to get out before that last crash". As bitcoin gradually monetizes.
It will eventually get to those absurd numbers, and by then, it won't seem as absurd anyone once it is the present and reality. And by absurd, I'm talking about the Hal Finney numbers of $10m, to the other projects that I have seen going up as high as $50m to $100m per whole coin.
We just need to live long enough to see our BTC pay for everything we would ever need (assuming we have say 1 BTC, and we don't need anything more than $50m to $100m in our lives.)
