I'm a big picture guy - I see broad strokes and connections.
What I see is that we have been using the horse and buggy of cryptocurrency since 2008 and it has served us well. However, the combustible engine (of cryptocurrency) was just invented.
Is it perfect? No, but it's light years ahead of what we've been using.
Will it be all that civilization needs, forever and ever? Maybe or maybe not - but it's the next step and it's here now. There's no use arguing about adding small motors to horse carriages when you have the real-deal you can use instead.
Nice view on the matter. Bitcoin may not be the perfect engine there is to satisfy our needs, but it was indeed one of the (if not) the first of its kind to revolutionize the way we see money. Sure there may be something wrong on how we achieve x and y through bitcoin, but it greatly improved how we value money and how we look to it. There might come a time that we might be all using bitcoin as a part of our daily transactions, and there may also come a time that we may still be using fiat or any other successors of bitcoin that proved itself that it is much more ideal.
