I fully believe Simon thinks he is talking to Q. He also, however, believes that quantum computers can look at different future timelines, in free energy, and that we are going to become 5th dimensional beings. The only way any of this is true is if there are aliens who are giving us technology way beyond our current understanding. Are there aliens, Simon?
The reason he is so believable is because he seems to genuinely believes the stories himself. However, he has yet to make a single, provably correct statement about this whole election debacle. He also gets angry if you try and question his failed prediction history. In short, the man does exhibit classic symptoms of delusion and some kind of neurosis.
That doesn't mean he isn't correct on some things. But he could also be a tool under the influence of either side. You need to be very, very careful trusting anything such a man says.
