20-Year Prospect
Just like "there's an app for that" seems to answer every technological query these days, "there's a machine for that" feels just as applicable. The manufacturing industry currently relies on CNC machine tools and automated/high-speed machining. For old-school, conventional machinists, this is a problem—it's one of the reasons the industry has an incredibly low, 7% growth rate (source). More and more workers are getting replaced by precise, automatic machinery.
But if you're determined to be part of that 7% who gets added to the job market, there's a tiny sliver of hope for you: become one of the folks trained in working those machines. By learning about the machines that will eventually replace you, you can make your place in the working world a little more secure. You'll eventually be able to transition into being a CNC programmer.
Expect to be crunching numbers and pressing buttons, not designing cool new products. The twenty-year prospects may seem a bit daunting, but if you're truly passionate about remaining in this world, you may be able to move the odds into your favor.
