There is always consternation amongst modelers about where the next generation will come from, but the Gundam/Gunpla scene is supposedly very large in Japan and growing in the West.
Adult-me recently took to designing a kit for a NASA "Space Tug" that never existed (only proposed "artist's renderings" from the 1970;s) [1]. It is so esoteric that no one made a kit for it — I had to learn to use Blender, ha ha.
I just wish more kids were into modeling.

I had hoped that learning Blender would pay dividends in other types of pursuits as well since it is a fairly broad tool. And as you probably now, there are "mathematical" ways to use Blender — parametrization though is a bit lacking (without going down the plug-in rabbit-hole).
People are often too judgmental these days, and youth must make their own decisions about the world they want to live in.
If you know the history of how JPL started, than you can probably guess it is the "odd" ones that tend to change science for the better. =3
I'd argue that if someone wants to get started with building models, Gundam is the way to go. Painting optional, no glue needed, etc. Plus, giant robots are cool.
