Inability to cope with technology maximizing societies is kind of a special case. It applies to basically ALL animals, birds, fish, plants, and even to other humans who decided on being expedient technologists. If you can't call the Parlevar successful ("Before British colonisation in 1803, there were an estimated 3,000–15,000 Parlevar" -- Wikipedia) then you can't call any of the species successful that we wiped out or massively reduced.
