Flask's creator, Armin Ronacher, was asked on the Real Python podcast in July 2020 what specifically he would have done differently. He said he under appreciated how big the community would get but also the number of people who would use it. He faulted himself for not spending time thinking about the transition from him primarily working on it to others. And that he should have been thinking about how things would work when he was not involved. The specific item he was concerned about was that he did not work to build a "community of like minded people" which he says Django did a much better job at doing. At the very end of the comment, he openly considers if there are things he should have done differently: "I probably would feel less detached from it if I would have communicated some of my ideas more. I feel like it is no longer my fight to make it more backwards compatible for instance. The community sees this differently than I do, so that's fine." https://realpython.com/podcasts/rpp/58/#t=1202 https://realpython.com/podcasts/rpp/58/#t=1202
