Everything is centralized on the internet. People quite often forget that most of the internet backbone is vulnerable to all sort of attacks (BGP hijacking) or even just mass surveillance because most of the traffic is going through few devices. Unless I can directly reach your computer on the network without a 3rd party provider which can deny me that access you can't be seriously thinking about decentralization. Another issue that I see with these projects that claim to be decentralized, for example ipfs.io is that they do not consider worst case scenarios so they cannot have a service level agreements on their service. Most of the customer networks are asymmetric, you have much more bandwidth to download content than to upload so if you are providing services than you are going to saturate your uplink. Nodes can also be turned off, worst case scenario is that all of the nodes are off that has a piece of data that you can't recover from anywhere else. As of everything going to be built on the blockchain in the future, most definitely not. I think 2019 going to wipe out most of the cryptocurrencies and we are going to see very few successful blockchain (or more like distributed ledger) projects succeeding in the corporate space. Maybe there will be some use cases for blockchain/DLT like food traceability (one project i have contributed to) and customer warranty for example but all this hype that everything will be running on blockchain will just fade.
