Is Bitcoin the final form for humanity?
Decentralization has long been dreamed by all different social models, is there another step to be taken?
Can humanity (humans) learn to hang on and manage their finances?
Or is Bitcoin an experiment to show that we're not capable of managing our own belongings and do require central authority?
What do you mean by "the final form or humanity"? The human civilization is always evolving, there's nothing final here. Finance is evolving as well. The people used gold and silver coins centuries ago. They moved from gold coins to paper money, that were backed by gold. Later on, they moved to fiat money(not backed by anything). I guess that the next step would be moving towards digital currencies.
There will be a constant battle between centralized financial infrastructures(banks, CBDCs) and decentralized financial structures(blockchains, crypto). I don't think that the governments and the central banks would just surrender and adopt decentralized technologies.
