I agree that input lag makes it niche, but niche and experimental can be okay. I think the real problem is their pricing model. Stadia is well set up for a Netflix style pricing model where you spend $X a month to try out an experimental idea that works well for some people but not for others. However, having to pay full price for games on a platform that might not work well for you and might even disappear in the near future is just non-sensical.
