No, I'm afraid I disagree, WB. The premise of Big Data has nothing to do with eliminating analysts, at least not as presented by any sane view of the technology.
Admittedly, know-nothing consultants may sell that idea to know-nothing IT directors or marketing VPs, but that's just smoke.
As you may know, Big Data arose from Google solving a particular problem they had with a particular data and computing architecture. As often happens with in-house Google solutions, when they published their result, everyone + dog decided to replicate it and then to apply it to all kinds of inappropriate problems, and then to apply appropriate but non-Big-Data tech to those problems under the same name, and somewhere in there the definition of the thing got totally lost.
That's when the consultants and tech bloggers and the market analysts at Gartner and IDC and so on started their feeding frenzy.
As it used to be known back in the Olde Tyme Days of the late 2000s, Big Data is a large distributed data store -- typically with weak or nonexistent ACID characteristics and a query language much less powerful than SQL -- capable of storing more total data than a conventional relational DB as well as heterogeneous data which may not even have any schemas known in advance. That data storage facility combined with a distributed computing framework for processing the distributed datastore -- ie Map-Reduce or something similar -- is a particular thing with a particular use.
None of this has anything to do with eliminating analysts.
To the extent that Big Data now means "any reasonably large amount of data, or any raw data, or any data whatsoever having to do with marketing or demographics, or really anything at all which will convince you to buy my consulting service", well sure, maybe somewhere in there "eliminating analysts" is at least a marketing goal. But that's not a feature of the underlying technology. Perhaps there has been some confusion of Big Data with the NoSQL movement or with other disintermediation movements in ICT intended to distribute authority to business units and executives with purchasing power and away from IT specialists.
