When a vessel makes it into space, there’s a system in place which ‘expects’ your onboard computers to synchronize with it.
This system does things such as learn about your computer systems and how your computers function.
It also does things like pore through your database(s) and learn about your society and worldview.
It downloads pretty much everything including the vessel occupants, views on life and death, and attempts to understand anything and everything there is to how you see and understand the world.
It works on both analog and digital computer systems.
And doesn’t need a computer to connect to.
