I think alot of things supposedly already being done and the profit based bent of the world discourages young developers who don't know that half of the touted projects are crap in many cases and there is still large amounts of room for development.

Not to mention the glaringly obvious security hole and the need to build teams that understand the comp from top to bottom so certain scheisters can't push bullshit on us that would take a single person too long to understand every aspect of.
