I don't manage to make Gemini treat any topic, is there a method or is this IA simply not suited for learning/studying?

I am losing my sanity trying to learn things with Gemini, I spend hours just battling with it to end up leaving confused and more ignorant than I was initially.

My problem is firstly that it's extremly vague and only produces short answers, if I asked for longer answers it just inflates it with pompous phrasing instead of providing higher level of informations, and if I ask for a higher level it will just name drops references or definitons that are only understandable for someone who already knows the topic. Basically I am unable to create any explanation of anything with Gemini. It also has a tendency to simplify and vulgarize everything.

Example: I ask gemini to explain RNA, it will either tell me a useless infantilizing definiton with metaphors or "bricks" and "little workers", or it will give me a straight up ununderstandable definiton summarized in 2 lines, if you ask to be more precise it will just keep going on with sentences that only someone who don't need explanations would understand, if you ask about something specific in the answer he will fragments the topic and produce a new answer only about this very specific thing you didn't understand, answer that will again be either too simplfiied or ununderstandable, and it goes on and on.
