Mac Fan Portal publishes interview with Ami Otsuka
On March 26, 2025 Mac Fan Portal published an interview with author and app developer Ami Otsuka (representative of Hundreds LLC). The title translates roughly as "Programming with ChatGPT: can anyone do it with generative AI? Not quite. A punishing challenge. An interview with Ami Otsuka, author of #100 Days Challenge." It was written by Yuki Yamadai.
In the interview Otsuka names two things that were needed to keep the 100 Days Challenge going: her own curiosity, and an incentive.
The article also records that she started the challenge on a Windows machine bought for 80,000 yen, that a professor handed her a MacBook Pro on day 31, and that Hundreds, the company name, is the plural of one hundred.
