Quantum computing conundrum roll

A recent Wall Street Journal article doesn’t hold back on the hype, at least in its headline. Quantum computing, it promises, will change the world as we know it. Courtesy of Google. The story that follows is a bit more measured. The obstacles to successful quantum computing are discussed, the murkiness of the applications is considered. There is a discussion of activity of some players - Dwave, IBM, and especially Google. Also noted- The NSA is building a quantum computer too. The conjecture is put forward that the nearest closest biggest opportunity for quantum computing relates to machine learning - guess because probability is involved and the computation problems could grow unmanageable eventually. We will see. 

The most obvious expectation is that the NSA is anticipating the possibility of a point where quantum computers could break important codes. And thus disrupt the present status of Internet commerce. Is that as big a threat as Hitler? I ask that because there are parts of the quest for quantum computing that bring to mind the atomic bomb program of the 20th Century.
