some questions, inspired by google wave and one discussion.
1. are Google Maps useful or harmful (yes-no, why)
2. will the 3d map of the world (or your city, country etc, if it will be available) be useful of harmful? (yes-no, why)
3. will be useful or harmful such a map together with the real-time (delay<10sec) information of people’s movements
4. and 3d map with moving objects, updating in realtime (delay < 1 minute)
Technically, all 4 cases are possible even now, though the latter would need lots of money to invest to build the infrastructure.
