At the moment, any answer will be fantasy and speculation, if I understood correctly about 220 millions of years: Lets rewind 220 million years and lets implement humans at that stage as the alpha mammal.
One of big pieces of puzzle is Space and we are not in space at the moment, but that might change our priorities in civilization development, and as we on WB I can freely say, if we discover possible presence of hostile aliens as example, it might greatly shift our perception of what we have to do.
That stupid question is there live on mars, titan, or on any rock in space which we have observed atm - which(question) is discussed each time to create public hype, for glory and money.
But answer on that question is vital to be able think about live and its destiny and what might happen on such large timescale.
Yesterday someone shared that link to me, and I wish do the same: Dr. Robert Zubrin with a brilliant answer to "Why Should We Go To Mars?".
Second important moment of Space is that we do not understand its practically possibilities for us. What can be done, what have sense to do, why it is better this way and not another way.
One of its kind, there is channel on youtube
Isaac Arthur
- I would recommend to watch, it is about space and some space capabilities.
We can't say at the moment what will happen, but we can say what will not happen.
Our style of live will change in less then 40000-6000 years in case of noFTL and few 1000 years more in case with FTL, just because of energy constrains. Some thoughts about that in my answer to Q What would come first, the colonization of the solar system or interstellar colonization?
And this is another main flaw of prediction something over 200 millions of years. There is almost no difference in asking about 10k years in future or 200kk years of development, and no ways to foresee that, no examples and not enough knowledge.
But as you asking, I strongly recommend take look at links I have provided, specially on youtube.
