What are some of the significant rules used by technicians who want to follow the smart money and what is the logic of those rules?

Question 6: Though many electronics students and professionals alike associate semiconductor components with the word "digital," electromechanical relays are also digital logic (on or off) devices. In fact, some of the first digital computers were built with electromechanical relays as their active elements. In what ways are electromechanical relays similar to semiconductor logic gates? In what ways do the two digital technologies differ?
