It's hard to differentiate between transients and steady-state on a short time-line. The "research factory" model, I believe, is a transient, at least in physics, sustained by the low-hanging fruit left between industrialization and now. Progress is slowing down asymptotically approaching zero. And I think that's okay - consider that the progenitors of the current approach all had day jobs, all of them did this in addition because they HAD to do it. As long as society allows people to have sufficient free time, we'll still get progress in the foundations of physics. (Note that this argument does NOT apply to capital intensive experimentation, e.g. the LHC, space telescopes, or fusion research).

Journeyman physics isn't all bad, and in fact can be quite good. Not only do you not have to worry about the social, administrative, political and funding headaches of academia, you are also not suffused in the always reasonable-sounding groupthink that persistently tells you what can and cannot be done, what should and should not be questioned. I strongly believe that the next truly big shift in physics, if it ever comes, must come from an outsider. (And if that happens, ironically, we'll have another period of fruitful professional academic physics, and later another iteration of this same discussion).
