I don't want to talk about theory, let's learn on history.
Short example. Nicolas Tesla was a briliant guy. He invented a lot of devices which we use today. But he died in poverty, because he didn't care about people and investors (putting simple: PR). But Edison did care about people and investors. He was not brilliant, but he's company - General Eletric exists till today. Eidosn didn't die in poverty. Tesla did, because he woas focused only on "the thing" not "the people".
You can usually read whatever you like into history - e.g. if Edison had followed your argument then he may have decided to focus too early on his core skill of telegraphy.
I agree Tesla was killed by his investors but basically because he was shafted by Edison. (I could equally use that to argue that being at the centre of technical developments and having lots of friends is crucial).
