Chill out

Every Doctor Who fan I've ever known:

Yay Billie ❤️

While I'd like there to be new episodes, I'm not super concerned about the future of the show personally. RTD said in an old interview (from his first run) that Doctor Who is like Robin Hood and Sherlock Holmes now, it's just part of the national consciousness and I think he was right. Plus, as Billie Piper alludes to, it had a 26-year run, went away for a bit (during which time there was still a stream of novels, audio plays etc.) then came back and had another 20-year run. I think worst case it cools off for a few years, we get lots of books, Big Finish does their thing and we probably get a lot of online fan-made things this time, then it'll eventually come back and do probably another 20-ish year run.

Or maybe something will come of the tender and it'll be back in a year or two (or three). Either way, it's not really going anywhere IMO.
