Hello redewenur,

you said:

"With the advent of intelligence comes the development of sophisticated behaviour and methods of enhancing the environment to achieve the survival goal. Information, therefore, becomes very important to survival and development, so it would be illogical to destroy a source of information unless failure to do so posed a sufficiently serious threat, or represented an overall disadvantage to the species."

Again I will be the devil's advocate- again we are assuming what is intelligence is, and assuming their belief systems are comparable to ours. The question to ask would be how did their beliefs evolve and what interacted with their development to make them what they are? Perhaps they don't want to destroy, but change things a little, to see what would happen if.....
Perhaps their desire to learn is their religion. Just a thought,and if this were so,for the sake of conversation merely fictional, how would you have a dialogue with this kind of being?

best regards,

People will forgive you for anything -but being right !
