There are far more programmers now than in 1980, yet the average programmer makes far more (inflation adjusted) now.
That's why sw devs salaries went up like crazy in our time and not in 1980.
But what new tech will we have, that will push the SW dev market demand up like internet connected PCs and smartphones did? All I see is stagnation in the near future, just maintaining or rewriting the existing shit that we have, not expanding into new markets.
How will the job market look like when it's all rewriting and maintaining the existing shit?
