Establishing the history of human expansion to space

Hey guys, ive been working on the history of my humans expansion into space and while considering sol system colonies, space stations and developing factions. I've found that the Expanse series depicts a very likely scenario of humanities future in the sol system.

I've been working on my own ideas of how humanity develops with my own spin on events. For example humanity develops similar to the Expanse but the development of FTL leads to a massive exodus from the sol system and the collapse of a unified earth.

Space stations are left abandoned or unfinished, colonies turn ad hoc to become self sufficient and the sol system comes under the management of whatever faction that stayed behind.

What spin do you guys have on the future of humanity?
