Total replacement won't come until things are completely seamless, but it's definitely happening. Especially in cars. It will just become completely seamless for you to ask your car to display directions from Google maps as an AR projection on all the vehicle windows.

At that point the lines between reality and virtual will blur and AR will be the default interaction.
