I don't believe that the world will become so "digitized" as you describe it.What about the poor countries in the third world?Do you think they will become "digitized"?However,to answer your question about what comes after bitcoin.My answer is...nothing. 
The blockchain technology might be adopted in various industries,but all cryptocurrencies will become obsolete.

I do think the poor countries in the world will also be affected. Satellites will soon make internet access a global "right." https://www.geekwire.com/2018/spacex-gets-set-launch-first-prototype-starlink-satellites-global-internet-access/
Why do you think cryptocurrencies will become obsolete? What indicator are you basing this prediction off of?
We don't know really on what to become on Bitcoin in the market, all of the negative news are affecting the crypto market, the consumer's behavior or level of confidence are dropping as shown on the market, a lot of sell off as the price value of Bitcoin dive further, i am still optimistic on the market recovery after such market drops as posted, one should look into the market movement, it seem the market is stabilizing now at the level of 4k but a lot of negative speculation on the status, is this the new resistance level of Bitcoin? will it goes up again? a lot of question which affect the consumer's confidence level. Be patient instead and wait....
