We spend 99% of our time on the applications and the rest on improving the tools we use for application development. Until someone (with control of the purse strings) sees the value of having people actually work on the tools, this isn't about to change....that, regardless of *where you're at* on Bob's line of ever-increasing automation, your *movement along* that line, towards the point where you've automated yourself out of a job or career, is rather slow. 'Coz the rate of movement oughta be more or less directly proportional to the proportion of time you spend working on the tools, I mean.
Note that this is of course disregarding the possibility that you use tools *other* people make, which *they* spend pretty much *all* their time on: For the purposes of a wider discussion, the percentage should be industry-wide, not company-specific. (Which brings us neatly back to your question about how to define "industry"! :-)
