I have done drawings, and I was very good at it, long before CAD came around. I might add that I have experience doing so on military aircraft. So, I can speak from my personal experience of using the different methods of reading product design from creating and reading paper drawings to 3D solid models with value added 3D GD&T.
The "technologies" you speak of to view and read 3D solid models with intelligent value added 3D GD&T are far cheaper then the capital and maintenance cost of plotters and the paper.
Here is a real life example of through put. I worked for a company, although using CAD, plotted all the drawings, which were checked by checkers using red, yellow, and green markers. I changed that process, although using 2d drawings, the drawings remained electronic and I trained the checkers to use only what they needed to mark the drawings up using basic cad skills. The difference was a 700% increase in work throughput and far far better retieval (reuse) of the corrections to understand and learn (teach) to begin to eliminate constant errors and gain significant consistency. Doing a similar but improved process with 3D will gain similar results.
BTW are you familiar with the new PDF capability to view 3D models and the 3D annotation? Might want to look into that.
