A sincere question that I have often: what if the jobs these people land (and that many that we here do) are _not_ Hollywoodian at all? What if that does indicate that a lot of the things we can do can be done by someone with this level of experience and aptitude?
Like everyone else, I also keep asking myself the same thing. One thing that helped me was to read more about Existentialism, especially the work from people like Camus or Sartre.
TL;DR there is no meaning or even the necessity of having one. Existence comes first, each one of us can craft their own meaning.
