Tokenization of everything will mean that everything will be a subject of econonic valuation. And I think it's one of the biggest issues of humanity, that we're stuck in the economic-value-based mindset.
The economic models of these tokens are going to be varied and as a result, they will incentivize different kinds of behaviors, some good, some poor. However, since we all work on incentive of some kind, if we want to reinforce positive behaviors, we have to value them - not only value them socially, but also economically.
I believe it's precisely the problem: we may use the blockchain, but we're still stuck in the old paradigm, where we only care about the valuation of everything. What's the difference how we then reward people? They are still just a value-producing machines waiting to be put to work.
This will not be restricted to online activity either, as it will increasingly leverage the growing Internet of Things (IoT) where smart products will be able to becoming faucets and tools for mining.
Which, for me, means that there will be only less and less spaces where I can still just be a human, and not a pawn in the economic calculation.
Anyway, these are my biggest fears which do not allow me to be so optimistic about all these changes. I'd like to elaborate on this in the future and open up a discussion, will be super interesting for sure!
