This is no mere flight of fantasy. Dr. LaVey presented this topic
and expounded on it.
The artificial human companion that Dr. LaVey envisioned took on a different form. You are sitting in front of it now.
However, there have been other advances, notably in realistic life size dolls seen in the sex industry. Here is but one example.
To answer your question directly, yes, this is a goal as spelled out in the Pentagonal Revisionist program, and yes, the artificial human companion would serve its owner/s in whatever capacity they are designed for.
While you may have concerns as a natural freethinker, as a Satanist, I don't.
