You CANNOT decentralize everything. Decentralization inherently has certain strengths and weaknesses. A lot of activities and platform will be on a scale of being remotely to totally decentralized.
The internet as we now know it is truly decentralized information. With cryptocurrency, we have decentralized money. So, when many facets of information and human interaction becomes decentralized, it will be easier for segments of society to adopt it. Especially, the youth and tech savvy folks.
Let humanity be on a path to decentralization but with babysteps. 😊
