Why does every single nerd want to be the ‘Idea Guy’? I’ve met tons of people who want be the ‘Idea Guy’, and they’re were all idiots like Bob.
Easy, watch me be an idea guy:
So I got this idea for a great movie. It's fantasy, takes place in a forest that's a maze. And if you cut down trees to make a new path new trees magically grow somewhere else so it's still a maze. And there's some teenagers, they want to find their way out of the forest, but everyone tells them you can't leave the forest. They explore and closer to the edge there's these weird monsters that are like spheres that roll around and grow giant shark mouths to eat people who wander too close to the edge. And the sphere sharks seem to be ignoring, then later controlled, by this man who's got one eye and looks like a forest dweller except you realize later on he's got a revolver on his belt. And at the end of the movie the kids beat him and leave the forest and find out the world's like techy and dystopian. The sequels will be about the kids bringing down the techy dystopian regime that kept them in the forest with the sphere sharks, and they'll meet and be helped by a secret coven of witches who control the trees or something.
There ya go. That's all they think there is to being an idea man: Dumping a few paragraphs of stream-of-consciousness worldbuilding without any concern for actual characters, internal logic, practicality, entertainment value, or whether you're ripping off something you heard of a few years ago and forgot about. All
those things are the bland maintenance work we farm out to our less inspired subordinates. (Well, except that one about ripping off, that simply doesn't happen. We never rip off, we're
inspired.)
TL;DR Every would-be "idea guy" thinks ideas are rare and wonderful, and that implementation is easy and requires no work or talent. In reality ideas are common and 90% shit, and implementation is hard and requires a TON of work and talent. They lack both the ability to do the hard work and actually implement their ideas, and the self-awareness to realize it. Also, their first idea was that bad ideas are a thing other people have.
TL;DR the TL;DR: Idea guys can only ever create ideas. Nothing else.
("Idea" doesn't look like a word anymore. Dammit.)
