Seems like confirmation bias. We often than not like to lionize successful individuals, but plenty of visions are false or otherwise fail. On the other hand, we tend not to remember group efforts because it's harder to remember multiple individuals at a time. But surely they do exist. Was there a single visionary behind Bell Labs? Xerox PARC? The traitorous eight? The Apollo program? The Manhattan Project?
There are different types of group governance and almost all of them having an individual decision-maker at the front. Oppenheimer directed the Manhattan Project but he wasn't a "visionary individual," he had plenty of talented geniuses working under him.
I believe there would be a single polymath who has skills in multiple fields, such as Oppenheimer who was great at science and administration who can lead a group for successful execution. For Apollo moon mission, it was the US president vision at the foremost. Even for TSMC and other companies such people exist. I don't want to say that entire credit goes to an individual but leaders with multiple skills are necessary.
Nah, this is not true. This is just the narrative because someone want to get the honors or the stacks of cash. Apple wasn't created by Steve Jobs. Not even created by Steve Jobs and the Woz. They did start something that eventually became Apple. They had a lot of sway, but without all the other people that worked there and created all the important details it would have just been a pipe dream.
