We've been discussing Google BigQuery as serverless lately. It's a nice succinct way of saying "fully-managed" + "no-ops" + "no resource deployment" + "seamless scaling" + "separation of storage and compute" + "deployed regionally" + etc. Some customers talk about BigQuery as "Data Center is the Database". So these buzzword help describe what BigQuery is and how it is different from other analytics services and technologies.
In any case, if a buzzword helps get across some meaning, sure, go for it. Folks just get carried away :)
