Steven Spielberg (born 1946) is an American filmmaker.
By the 80s, one person could make a movie on their own. That doesn't mean every movie made by one person was a brilliant masterpiece. It meant more people could make amateur movies and occasionally some of those amateurs, like Steven Spielberg, who started making home movies as a kid, get really good at it.
