I do 3D printing as a hobby. I don't see it replacing everything. Certainly, there's a lot of advantages to 3D printing, but I don't think it will replace everything eventually, at least with the current technology we're using. You can't really beat injection molding in term of throughput and cost at the large scale. Certainly 3D printing will become more common, and bigger 3D print farms will open up, driving down costs, but will never reach injection molding in term of being cheap on a large scale. What 3D print farms can do is the ability to change what get produced on the fly allowing responsiveness to market demand. Really, a lot of the amazing stuff in 3D printing are things people designed. If you know CAD, the world is your oyster.
