Russell T Davies thinks the world is ready for a female Doctor.
The 54-year-old screenwriter and producer - who worked as head writer and executive producer on 'Doctor Who' for four series - is excited about Jodie Whittaker having taken over the famous role.
Speaking to Doctor Who magazine, he said: "Why look back? The future is golden. Already, the new show has got the best logo it's ever had. I love it. And okay, look, I know, some of us might be worried about the changes to come.
"I worried, out loud, in print, once or twice, back in the old days, about the reaction to a female Doctor. But d'you know what? That was 13 years ago. 13 long years. I've grown up, and learnt, and I hope I know better, and the world has grown up too."
Back in 2006, Russell said casting a female doctor would "pose too many awkward questions".
He said at the time: "I wouldn't cast a female doctor. I think it would pose too many awkward questions. I'd be worried for the parents, having to tell their children why a man has become a woman and how they would explain it to them and how it would work in real life."
Meanwhile, Jodie previously admitted it was "completely overwhelming" to be the first female Time Lord.
She said: "It feels completely overwhelming; as an actor, as a woman, as a feminist, as a human, as someone who wants to continually challenge themselves and not be boxed in by what you're told you can and can't be. I want to tell the fans not to be scared by my gender because this is a really exciting time and 'Doctor Who' represents everything that's exciting about change. The fans have lived through so many changes and this is only a new, different one, not a fearful one."
Despite her excitement, Jodie didn't feel daunted when she auditioned for the part.
She said: "I went to the audition excited, but I always walk into the room with an attitude of 'I sound like this, I look like this, but, believe me, I can do it'."
