Aside from cryptocurrency, blockchain is now also into digital immortality

[CarTrick]

Within the next 50 years it is highly likely that we will have DNA storage technology, capable of holding an immortal blockchain with infinite data. 

At this point we could even start storing all of our existence in a way that could be ingrained in a newborns psyche, giving them a base to continually develop and learn from.

Interesting read. With blockchain and AI, storage of data will be easier and more efficient and I don’t think there’s a limit to how much data in can handle. I think it’s possible to be digitally immortalized. I’ve even read about the digital storage of memories, so I think it supports the claim of OP.
