I can't make that assumption. Any one of these crafts: direction, acting, editing, cinematography and soundtracking is always hard to find. You always had to wade through a mountain of garbage. The way most execs did it previously is through word of mouth. I don't believe that's changed today.
That's exactly what I meant. It becomes a real problem when you're looking to fill a technical spot. It's really no different than casting actors, though – that's always been a flood of wannabes. My point was just that lowering the barriers to entry on the technical side means more people feel qualified, even if they aren't. Practical issue more than an insurmountable obstacle.
