If you want to see the future of modeling, just go to model train show. It is attended mostly by men in their late 60's and up. That's what they grew up with. Those of us in the mid 50 to 60 age range grew up with plastic models. Yes, modeling will probably only continue to become more of a niche hobby. Just look at the volume of each subject model produced. In the 60's one single model sold a million units. Now it is more like tens of thousands at the very best, most are much lower. As for as younger generations interest is concerned, the average age of teens getting their drivers license is steadily going up. More and more they see cars only as appliances. A lot of the interest by younger people is in foreign cars. That's what they grew up with. Times have always changed and they will continue to do so long after all of us are gone. We are lucky to have as much being offered as we currently have. If their was really enough interest for newer subjects, the most likely be produced.
