I agree with you.

In the book zero to one, the author argues that no one man can build a great thing. Of course there are exceptions.

Also, in the book The Wisdom of Crowds by James Surowiecki, this author explores how large groups of people can make better decisions than individuals or experts, if certain conditions are met. The book argues that collective wisdom can emerge from the aggregation of diverse opinions, independent judgments, and decentralized information.
