Ethereum co-founder Vitalik Buterin published an action plan for the next 5-10 years.
It covers not only the Ethereum 2.0 network, but also the later stages of ecosystem development.
This is my approximate view of what the next ~5-10 years of eth2 and beyond might look like.
Roadmap below reflects my own views, others (including future versions of me) may have different perspectives! Details may of course change as we discover new info or
new tech.
