on point 2 another way to put it is that digital computers take much much lower tolerance components than analog computers. A digital computer transistor has to operate(assuming ttl logic) at around 5 volts and 2 volts the transistor behavior in between does not really matter. The analog computer transistor has to operate to a high precision at all voltage ranges. Go ahead and start pricing out high precision transistors and the environmental controls needed to keep them there and you will see why we use digital computers. The history of the navy NTDS air defense system is interesting because they were in a position where they could have gone ether way. use known and understood analog computers or go with the unknown new tech, digital computers. https://ethw.org/First-Hand:No_Damned_Computer_is_Going_to_Tell_Me_What_to_DO_-_The_Story_of_the_Naval_Tactical_Data_System,_NTDS https://ethw.org/First-Hand:No_Damned_Computer_is_Going_to_T...
