Let me lay it out for you more clearly to better illustrate my point.
I don't give a single solitary fuck if you're the first man to step on Mars or some dude sitting in a sewer scraping shit off a wall. As much as I respect your experience, your job, and said experience in a dev environment in an area that supports a good enough infrastructure to allow you to stream from your workplace to your house and play vidya means nothing to me in this situation. I never said I doubted the ability for the backend to support this type of system. On a small scale in a controlled enviornment where you own all the pieces to the jigsaw is a big motherfucking difference to Jonny Cornfield sitting in the middle of Iowa trying to stream assassin's creed to his 14 in' flatscreen on 10mbps internet. If we were discussing something like "OH THE CLOUD WILL NEVER WORK FOR ANYTHING", you'd have a point here since yes, you have more experience working with it than I ever will. But that it's what we're talking about. I'm a customer who will be potentially using this product, and I'm looking at it from that perspective. I don't care about the dev side or how well it works, that isn't my job.
See where I'm going with this? It isn't just a matter of 20ms of extra input latency or some shit.
Yes, comfy that you can make it work and you have experience with the backend of something similar to what Stadia will operate on. But you, and no one else like you, can tell me or any other consumer, aka the people who have a vested interest in this working just as much as you do, that it will actually fucking work properly for most people. Your work and experience with these environments also doesn't tell me how google can or will monetize this system. No, I'm not willing to trust a multi billion dollar international corporation without seeing it first, decrying skepticism is absolutely fucking stupid and I know you're smart enough to see why.
Edit: I just read your tweets. I don't even know why the fuck we're arguing we're saying the same shit.
