Apple CEO Tim Cook sat down with Stephen Colbert on The Late Show tonight, and while it started out as little more than an iPhone 6S showcase, the interview eventually touched on more personal things like Cook's feelings on recent Steve Jobs movies and his own decision last year to publicly come out as gay. "I have to admit, I feel a little naked," said Cook as he sat on stage without the teleprompters that keep Apple's executives on track at the company's keynotes. But then he settled in, demonstrating new iPhone features like 3D Touch ("It saves you so much time") and Live Photos ("The photo really just comes to life").

Cook swerved around questions regarding Apple's car plans, saying only, "We look at a number of things along the way, and we decide to put our energy in a few of those."

"People are trying to be opportunistic, and I hate this."

Then Colbert asked Cook for his thoughts on films that focus on the life and career of Steve Jobs, Apple's co-founder. "I haven’t seen them, but the Steve I knew was an amazing human being. He’s someone that you wanted to do your best work [for]. He invented things that I think other people could not. He solved problems other people could not. He had this uncanny ability to see around the corner." And while Cook hasn't seen Man in the Machine or Sony's Steve Jobs, he doesn't seem pleased with the trend. "I think that a lot of people are trying to be opportunistic, and I hate this; it’s not a great part of our world."

The conversation then shifted to Cook's lauded Bloomberg Businessweek editorial last year, in which the CEO revealed his sexual orientation to the entire world as a show of support for those who still regularly face discrimination over who they are. "Where I value my privacy significantly, I figured I was valuing it too far above what I could do for other people," Cook said. "And so it wasn’t a revelation for a lot of people that I work with, but it was maybe for the broader world. And I felt a tremendous responsibility to do it."

Tonight marked the first time Tim Cook has visited one of TV’s marquee late night shows; he has largely stuck to news-oriented programs and renowned interviewers like Charlie Rose. But alongside the regular rotation of celebrities and sports stars, Stephen Colbert is making tech luminaries a staple of his Late Show. In under two weeks, he's already had Elon Musk, Uber CEO Travis Kalanick, and now Cook on the program. To wrap up the segment, Colbert asked Siri for one last question; Apple's digital assistant told him to ask Cook about getting her a raise.

Cook's Late Show interview comes a day after he made a surprise appearance at Apple's flagship Fifth Avenue store in New York City. It's a big month for Apple, with iOS 9 due to launch tomorrow and the company's iPhone 6S and 6S Plus slated for release on September 25th. Just last week, Apple mapped out its plans for fall products; aside from the iPhones, a new Apple TV is coming in October, and the massive iPad Pro will round out major hardware releases in November. New Macs may also be on the agenda, but with Apple unlikely to hold additional events this year, they'll likely be announced with little fanfare.
