There's options besides jury and no jury.
You can have a selection process where the prospective juror has to pass a quiz with some basic deductive reasoning questions. You can have professional jurors who have to take a class. You can have a panel of judges acting as a jury.
It's also taken over 200 years to get juries to stop doing things like putting weight on pleading the 5th (in criminal trials)
Pleading the 5th will harm you. The prosecution will bring somebody to weave a story in front of the jury. If you don't take the stand, their version of the story becomes much more believable. I suspect there is something innate about believing people who claim to have experienced it talking directly to you. You have to be extremely analytical to look at the physical evidence that contradicts the narrative and actually believe that over your gut feelings.
It's the same type of legal fiction as pretending every person knows every law.
If you want it to work properly, you have to stop allowing anyone to take the stand. Letting people take the stand, especially victims, create an emotional bias and unfairly helps people who are good actors.
I'm sure it'll take another 1000 years to fix issues with juries, and I'm sure these days AI is probably going to be a thing as well.
I think another 20 years probably. People don't really want to be jurors. The moment they can hand it off to a good enough AI, they'll go for it.
