Google is notorious for abandoning past projects. They are of the "try everything and fail fast" variety, and I wouldn't trust my money with their hardware. Not even software, except for Docs and Gmail.
This is why I feel like Stadia is doomed to failure from the start. It took Microsoft failing for an entire generation, even when they brought some new technology to the table, to start seeing real mindshare in the video game industry.
I don't see Google running a service at a loss for half a decade.
