My general experience with things like this from Google is to assume that this is at least one big step behind what they're doing now internally. Taking a position on how useful one finds this today effectively insulates from thinking more seriously about what could be done. If taken from a perspective of "what hints are laying around in this blog post or scientific articles about what's possible?" it's probably more effective use of time if you're going to invest time in reading it.

As an example, as you're reading it, try posing a few relevant counterfactuals.

What they are doing internally after launching something like this is patting themselves on the back, updating their resumes, and promptly forgetting it exists.
