Demonic Machines and Mechanisms

In the same way that the internet and highway system feel abstract enough and ambient enough, NOT to possess conscious preferences or personalities, are their any Demonic machines that can be evoked?

Things that still need a proper ritual/ mindset to make contact, with the ancient origins, unfathomable depth, and moral abiguity of the personality of demons, but without a consciousness, that desires, evolves and changes with experience?
