For everything to become incredibly amazing. 5G was more pumped than AI, especially in Europe. For some reason people kept mentioning robo-surgery as a use case...
There were two parts that were hyped: Lower latency, and mmWave. I think the self-driving cars and telesurgery kind of hype came from the lower latency part. Can't have a callcenter staff remote-drive a car that is stuck in some weird situation with 600ms ping.
