I spent a couple of days in Japan (mainly Tokyo) for visiting the National Institute of Informatics (NII) and attending the 27th ACM International Systems and Software Product Line Conference (SPLC 2023). I have been involved in several scientific activities:

• talk about deep software variability and reproducibility/replicability in computational science at SES 2023, IPSJ/SIGSE Software Engineering Symposium in Tokyo, Japan
• talk about ChatGPT and reengineering variants
• talk about ChatGPT and programming variability/variants
• panel about intelligent software product lines: I defended some ideas (eg intelligent assistants for exploring variants’ space) and research directions (eg generative AI for software product lines) https://twitter.com/FortzSophie/status/1697133197686173933 https://twitter.com/FortzSophie/status/1697115284300235072
• chairing of the session about feature model evolution and analysis
• steering committee of SPLC
• many, many discussions

Japan was truly amazing, I highly recommend, and we researchers are lucky to visit incredible locations and meet diverse people!
