The bar has been raised. If he can do it, and this kid is self-motivated and has a family/community supporting his efforts, what is stopping you or your church from investing in youth of this age to produce similar results?
As long as they learn a skill that advances what they will be able to do later, what they build isn’t as important as them getting the chance to learn how to build.
If you, or your church, has been doing similar, point us to the projects/results. We’d love to share in commending youth (or seniors) in these efforts.
