This conference is about celebrating YOU. 💙
So after chatting with a bunch of you, we made three changes to the event:
- We changed the name back to SF Ruby Conference.
- We updated our keynote speakers because, unfortunately, Garry Tan can't make it anymore.
- Day passes are now for sale.

When we say we want this conference to help build the future of Ruby, we mean it!
Our thinking is that if you talk to each other, you'll find repeated problems, come up with ideas to solve them, and build the future that we want/need.
This is how we learned about Inertia Rails. 🧵
