There are other intelligence tests beyond just technology, such as the ability to recognize a mirror for what it is.
orcas also easily recognize mirrors. i have watched many animals look into mirrors, and orcas and dolphins are by far the most interested and intrigued and show off many behaviors that easily show they recognize the object in the mirror as themselves.
of course there is more to intelligence than technology, which was what I was getting at. orcas use smooth pebbles as a massage center. they coordinate attacks with special roles, including behavior such as signaling to prey that they are leaving while leaving a silent orca behind to catch the prey as they relax. orcas are one of five known species, including humans, to go through menopause. they have complex social structures and dialects and have even been shown to communicate with dolphins.

this made me think about the relationship between intelligence and technological development. i think they are related but does technological advancement mean a species is really more intelligent than another species with less technological developments? i am not for sure. for example, i have thought about orca intelligence quite a bit. they are severely limited in their technological development simply due to their environment. the aquatic environment naturally prevents the recording of information and development of tools.
