It's hard to explain to normal people that if you have a stable internet connection and live relatively near to a data center and you buy a dongle and a cat6 cable to avoid any Wi-Fi interference and you enjoy playing certain genres of games but not other genres of games, then you can get a good gaming experience.
You have to be a technical person to understand the failure modes and most people aren't technical, get frustrated, and just say that it sucks. Cloud gaming is not a mass market product.
