Jean-Paul Sartre died in 1980. There were fewer than a thousand cellphones in the world. The World Wide Web was a decade away. He's the most prominent existentialist philosopher. There's no obvious connection between his work and this analysis of the impact of Wi-Fi on telephone companies.
As I write in August, 2015, it's not clear whether the panic telcos are demonstrating about Wi-Fi is justified. Verizon is running scared about the risk they face from Wi-Fi offload. That's the most powerful signal that WiFi is a real threat. On the other hand, Cisco and AT&T continue to project 40%-50% growth in data demand for four or five years at least. I haven't seen any convincing data to the contrary.
