I almost think moreso. I would almost equate it to an acclaimed author inventing the printing press.I personally love THX and Graffiti but other than those Star Wars and Indy he doesn't have a lot of variety to his name. Which is fine but as I've been saying for years I think his greatest achievement as a filmmaker and his creative legacy should be measured by his technical innovations as much as Indy or Star Wars.
Your art may be loved & long remembered, but allowing others to realize their vision is a much more significant contribution I'm my eyes.
