An anonymous reader writes: Writer and former software engineer Matt Gemmell adds his voice to the discussion about writing code as a profession. Gemmell worries that the latest "software Renaissance," which was precipitated by the explosion of mobile devices, is drawing to a close. "Small shops are closing. Three-person companies are dropping back to sole proprietorships all over the place. Products are being acquired every week, usually just for their development teams, and then discarded. The implacable, crushing wheels of industry, slow to move because of their size, have at last arrived on the frontier. Our frontier, or at least yours now. I've relinquished my claim." He also pointed out the cumulative and intractable harm being done by software patents, walled-garden app stores, an increasingly crowded market, and race-to-the-bottom pricing. He says that while the available tools make it a fantastic time to develop software, actually being a developer may be less sustainable than ever.
