The passages describe several practical implications of the coming "age of spiritual machines." These include computers exceeding human brain capacity by 2020, leading to human-level computational abilities shortly thereafter [Passage 2]. The passages also suggest the development of relationships with automated personalities who will serve as teachers, companions, and lovers [Passage 2]. Furthermore, information will be fed directly into our brains through neural pathways [Passage 2].
These advancements will blur the distinction between humans and computers to the point where machines claiming consciousness will be believed [Passage 1, Passage 2].

The passages do not elaborate on further specific practical implications beyond these described developments.
