No investor says "Well, whoever wrote this script obviously put a lot of effort into it, so here $50 million". But I'm sure hollywood community also encourages each other for their creativity no matter how crazy something sounds. Encouragement and actually putting in $50million are very different things. Everyone outside of silicon valley will react the same way you do, and that's why silicon valley is necessary because it's one of the few places on earth where you can talk about ridiculous stuff and not worry about being judged, which encourages creativity. (For example, most people will think "AirBnB for pets" is an idiotic idea and it probably is, but the fact that people can talk about these things freely is a good thing)
