To what has been said here, I can add that we should not rely entirely on new technologies, digital in particular. Now the climate is changing, scientists are warning of mass cataclysms, and any technology, including the Internet, may disappear. We do not know what will happen to cryptocurrency in 20-30 years, but descendants can find our gold in tens of thousands of years.
We are not the first civilization on this planet and the technologies of previous human civilizations sometimes surpassed ours. We find gold in all civilizations, but we have not heard anything about the use of cryptocurrency before.
If there weren't digital technologies such as the Internet, radio, etc., you likely wouldn't notice any climate changes or mass cataclysms because there wouldn't be any effective ways for scientists to spread their warnings. We wouldn't have the living standard we have today, humans would still be living in caves like animals. Or humanity would be already dead due to the lack of development of societies and technologies. We need new technologies, we need to develop new ways of dealing with old problems because that is how we survive and evolve. Even if we know for sure that the sun will burn out in five billion years, it doesn't mean we should stop building now. Today, the vast majority of people suffer from the disadvantages of the traditional monetary system, and people have to deal with it somehow by developing new digital money. Today, gold has failed as money but it doesn't mean it was useless previously or will be useless in the future.
