It's not so much hope as it is a belief in the inevitability of change. I'm not suggesting the trial is happening during his lifetime, and I'm not holding onto hope it may happen in mine either. Heck it may not even happen in the United States.

Trump cannot be president forever. That's just a fact. Even if they entomb him at the White House and make him the Eternal President Kim Il Sung style, that too will one day fall. Even if the US never prosecutes him, the world has to reckon with the consequences of his actions.

tl;dr - I'm saying one day, when he's out of office, someone will follow this up through criminal investigation. And those who will defend Trump, and there will always be some arsehole who will, will use the AI excuse to claim it was all made up then.
