Not exactly related to technology, but I wished for a LLM that could talk with me (and giving me valuable insights) about things like black magick, chaos magick, summoning practices and rituals involving literal "demons" (as in Goetia and demonolatry), as well as very dark poetry and enchants (texts involving very sensible elements symbolically and metaphorically, such as very deep gory goth). These "ethical boundaries" also affects how LLMs can talk about such topics, because LLM deem them as "dangerous topics" (especially Claude, a very sensitive LLM that even refuses to talk about Lilith).
