I loved the comment from Sid Ganis that Lucas possessed “an intuition that he stubbornly sticks by.”
That refusal to give up is such a key facet of becoming great at something. Many of our highest achievers somehow seem to relish people telling them "no." There are some wonderful stories of Michael Jordan being especially adept at magnifying tiny displays of disrespect or lack of belief in his ability, turning them to enormous challenges in his mind and using that to booost his motivation.
Most of the Lucas article highlights a certain ego sickness that seems to have taken hold of Lucas, a smugness that compells him to make rude remarks to the reporter -- "that's why you're here" -- and to bizarrely indulge in preemptive nostalgia for small, beautiful films that he hasn't yet made.
