Considering the handiness of smartphones, do you still use traditional technologies?

With all of the advancements that smartphones have given us convenience wise, such as Apple Pay, Smart-Door Locks, Smart Home Devices, Car Controls, Health Apps, etc, would you be comfortable moving all of your affairs to one location (your phone) for convenience sakes, or would you be prefer to keep all of these elements of your life seperate for as long as possible? (Keeping in mind there was most likely a time when even the usage of Calenders, Alarm Clocks, Timers, Notes, etc would be kept to traditional ways for fear of change.)

What do you all think? Personally I embrace change to an extent, and things such as Apple Pay are quite convenient, however I will always carry around even cash as a last resort, and my door locks will always be to a physical key.
