Stadia development is expected to pick back up as soon as the Google Fiber rollout is complete...
Yes they better because their advertising was at best misleading.
It seems like a terrible product to me from a "what kind of future do we want to live in" perspective, as well as UX.
There's no winning the PR game on Reddit or other social media sites when you have some motivated psychopathic shit-posters drumming up the negative sentiment - especially when the conversation gets titled that way early. There are a few sacred cows, but almost every other noteworthy game or console at some point goes through a similar phase. If the company keeps things afloat long enough while iterating on their product, the shit-posters generally get bored or move on to something else.
Many good products succeed despite it all.
Stadia is an amazing technology... and a fine product. Just fine. They go into marketing this thing with guns blazing, positioning it as the future to play games and the one-stop-shop, they better back that talk up hard. Stadia hasn't (yet). It very much smells like a disconnect between their business/marketing and the product development.
