How are we only getting one season?

So many things have been left unexplained that it's kinda absurd.

In the ending sequence of episode 8 it flashes ominously to dolls dead body, shows uzi flashing like a hologram, and in the ending song shows an absolute solver mass in a section labeled cryo pods? Which I don't believe we have seen before.

What was the absolute solvers goal anyways, To destroy all planets or is she just kinda silly?

Whats J gonna do when she makes it off of the planet?

There seems to be a massive amount of information left unsolved that could be put into a second season, but it's been confirmed (?) that there won't be one.
