"It's just not at all clear how to approach this problem."

Of course there are ways to approach it. Known ways; tried and true ways. Among them are 'logical analysis' and 'the scientific method', and there is remarkable little interest in applying either of those to the problem. Or perhaps there is great interest but little ability. All we know for sure is that results aren't being produced, and there's no functioning capacity to resolve that.

You are begging too many questions

I don't think this means anything. Surely someone begging the question is committing a single fallacy, and there's usually only about one opportunity for it in a simple argument - do you mean he's assuming several different things that he's setting out to prove? You didn't even cite an argument above.

Those things take talent of a kind that can't be taught.

Arts are those things that require skills that can't be taught - either because we don't know how or because it's not possible. Maintaining motorized vehicles is generally a science, but there are people whose expertise extends to listening to an engine run and tell what's wrong with it - without being able to explain what information they're paying attention to, how they're processing it, or how others could do the same. That's an art instead of a science.

"it seems like that's what most of the content here is about."

Virtually no content here is about that. At most, some of the material is about being about that.
