Nobody is born with finished skills. They have to be learned, developed, and practiced. Some people only have certain leanings toward developing a different skill set than other people. We had a couple sets of brothers and friends in our club over the years. One of the pair would most of the building, the other would do most of the flying.
We had at least one husband/wife team. The husband did the building and flying, while the wife did the covering. She could make iron-on coverings look like paint jobs.
Differentgift/skill sets. All part of the bigger picture.
A lot of people come into the sport/hobby through ARFs. Some move on (I am not saying UP) to building kits and plan/scratch building. Some stay with ARFs. A lot just get satiated and leave after a few flights or year.
ARFs are a part of life. They are not new. I've had a couple myself. I prefer to build my own, when I have time. Get used to them. They are a fact of life.
