"Are the days of the full-time novelist numbered?"
... asks Canadian sf writer Robert J. Sawyer. Unsurprisingly, if gloomily, he concludes the answer is "yes".
In this, at least, I am ahead of the game, never having been a full-time novelist to begin with. Sawyer concludes:
Maybe we will all indeed still be smiling as writing sf shifts from a career to a hobby. Still, lengthy, ambitious, complex works — works that take years of full-time effort to produce — aren’t things that could have been produced in any kind of reasonable time by squeezing in an hour’s writing each day over one’s lunch break while working a nine-to-five job.
I'm not sure that I'd go so far, but such a model suggests that publishers' appetites for the "one book each year" series may be on the wane. Maybe it's not all bad news.
