Low Tech

Why have the humans and dragons use very little technology?

While many humans are driven to seek the newest and fastest way of doing everything, that is not a drive our entire species shares. I can see a group of no to low tech settlers who would choose to use the hand methods of survival. Their children might want to explore the rest of the universe, but that can still be done by hitching outbound with one of the smugglers. Of course the connection to the planet would break… but that’s in a much later story.
