What's with the 10000 hours figure?

I suspect it's a selection effect. If a task can be effectively mastered with a short investment of time (like your example of 50 hours), then it's not something you can turn into a career. If a task can't be mastered in less than some large upper bound of hours (say, around 20,000) then it also can't be turned into a career. Tasks with a mastering time of around 10,000 are the ones that are pragmatic to specialize in and establish comparative advantage, so they are the ones that abound.

Any theories about why there aren't more 5,000 hour skills?

Well, my claim that tasks that take 10,000 hours to master are most common was pulled from the general vicinity of my posterior. If I were going to devote more than 4 minutes of thought to the topic I'd want to be a lot more careful about the whole question.
