It sounds like you're describing two different things though, of course, they can look somewhat similar from the outside. There's unable and there's not caring. I can imagine not having some specific skill sets and I can imagine just not having the interest in putting in the effort and learning what's needed. The results may look somewhat similar but they're different situations.
