Does it make sense to travel to a professional conference after you've retired? I decided to find out! How it went at the #Positconf2025 data science event in Atlanta last week:

Does Traveling to a Professional Conference Make Sense if You’re Retired? – My Next Chapter: A Retirement Journey
Attending in person isn’t a trivial expense, and some usual rewards like ‘career growth’ no longer apply. But I decided to go to a data science event in Atlanta anyway.

The slides from the talk are available at: shikokuchuo-posit2025.share.connect.posit.cloud

Waves to those going to #PositConf2025 this year. Especially to any other Scots/UK or #Disabled folk 👋. This is realistically the only way someone like me can attend conferences. Highly recommend joining the conference Discord server for realtime discussion around the sessions and finding your clan.

With @mapbox.com tools, we can model this with time-aware isochrones, then visualize on a map with a comparison slider.
