The question being considered by the author is one best considered while still working in a college or university environment, I would say. And it should be thought of in this sense: if I left academe today, would I still be working on this work? If the answer is 'no', stop doing the work and start working on something you're actually interested in. For me - and I suspect for most real academics (whether in academe or not) - the work is work we would be doing anyway.
