Talos Principle 2 Discussion [First game spoilers]

I've finally beat the first game and I'm very interested to see where the next one goes. Having passed the Independence test, The Child has left the simulation that the first game took place in and now seems to be in our world post-apocalypse. What will the world and puzzles hold without the trappings of the simulation? Will we hear the voice of the Serpent? What will be our goal? I assumed the in-world purpose of the project was to ensure sentience continued in some form but now what will we do with it?

Only things you need to spoiler tag are puzzle solutions and hints.
