The PSTN is the world largest network dedicated to one application i.e. telephony. It works really well, has great QoS and costs a few cents/minute. It has a great business model that supports around $800B dollar industry and employs a few million people around the world.
Look at another network the internet. Supports millions of applications none of which have any QoS, costs a bundle, Does not have a business model that works and employs well in tens of thousands.
Is something wrong here?
