It seems that most of the technological development of humanity is dependent on our ability to form a society. The sharing of ideas and building on the discoveries of others is how we have advanced. If an intelligent creature on another world tended not to associate with others of the same species, could that species have technological advancement beyond fairly simple tools?
I would think that a solitary creature, that only interacts with others for mating purposes, would not. I think that there would need to be some amount of communication for such a thing to be possible. However, there are many different degrees of sociality. How much socialization is necessary? Is caring for young until maturity enough? Or dwelling exclusively in family groups?
How would technology develop in less-social populations, and is there a limit to how much advancement is possible for them?
