There is a difference between Snapchat being worth $3 billion and Nest being worth $3 billion. The former gets the valuation based on users, the latter on talent and intellectual property.
Ditto here: $400 million is not buying you users, it's buying you raw talent and IP. Users can go off to another service in a blink of an eye - IP can't (talent can, but you can often structure the deal so that it won't for some time).
This could still be a terrible deal (I'm sure there are some people at Google still a little sore over Motorola, where the IP was valued far more than it ended up being worth), but for very different reasons.
Not to mention the enormous number of innovations they'll likely be able to churn out. Hopefully it's like an AI focused PARC, but with a competent tech company at the helm :-)
Though if they're expected to do wonderful things, and they've been doing things for years... it seems a certainty that they have already done some of those wonderful things. And hence have something concrete worth acquiring. Which would explain the valuation.
