20-Year Prospect
If we haven't sufficiently rammed it into your head yet, we'll try one last time: America's adults are getting old…and not dying as much. In fact, it's estimated that by the year 2050, over twenty percent of America's population will be sixty-five or older, as opposed to now, where the population of sixty-five and up is estimated to be about thirteen percent (source). That's a lot of people. A fifth of the population will be in the target market for your practice in the next thirty years (source).

Like most doctor-y jobs, this is one that needs a human's touch. No matter how great technology gets, robo-doctors are still pretty far off. Like at least forty years. Probably.
With the abundant supply of elderly folks and a complete lack of the risk of automation, you'll be sitting pretty in this line of work for many years to come.
