Anyone can learn to view timelines. Imagine I gave you an old black and white tv that let you see events. Some will be past events, some will be future events, and some will be "Mandela effect" events that may happen but on parallel time lines.There are no controls. You have to best guess if you are seeing past or future, how far past or future, who the players are, what the location is...That is how the old chrono's worked. Today we can start with multiple trained coherent conscious viewers and we have monster computers that have captured mountains of data (NSA) that can be cross referenced, we have dna data banks, face /voice / music recognition, we have AI and Quantum computers. All things are connected in this conscious web...and we have it all.
