Google Stadia belongs to yet another category: products that some people like and want and others hate and hope fail for social/political/economic reasons. AMP and Facebook Libra are other examples of products like this.

I hope Stadia fails because if PC gaming dies it will harm consumers broadly by further decimating the high-end PC market and reducing demand for high-end edge device CPUs, GPUs, etc.

We do not want a world where all compute belongs to someone else.
