i agree with Emily's opinion that GPS navigation devices is the most revolutional techonology other than smartphones.
First of all GPS navigation devices have allowed us to go to anywhere at anytime we want.
Not only do they let us know the routes to destination,they also provides us with the fatest ways to arrive there.
They analysis the current traffic jams and even show us the times to take.
In the past, when there were not GPS navigation devices, people must use map to go to somewhere even if the place is not far from their home.
They should keep checking the maps per minutes to make sure they were in the right ways and only trust the signs.
Before maps and signs are made, our ancestors should even use compass with magnet. If you were in this situation, could you make it?
This is how GPS navigation devices have been improved our life's quality and convenient.
However i disagree with Miles' assertion. Miles argues smart home devices are the most revolutionary technology other than smartphones.
I think that they are just assistant tools because we can do main things without them. For example, we can play musics without voice-activated assistants,
we can turn on our air conditioners or heaters without automated thermostats.
Thus, i agree with Emily's opinion.
