   It feels like things get thrown out just as fast as they're built.
   Quarterly planning? Long-term thinking? Some days they feel like relics of the past, so how do we build platforms now?
 
-  In this session, join Hazel as she walks through a journey of how she took a rapidly evolving environment, where a platform seemed impossible to build, and turned that chaos into something that long term success could be built on top of.
+  In this session, join Hazel as she walks through what makes a platform truly extensible, instead of just configurable.
+  Together, we'll walk through tenets of platform design that she uses to create platforms that can grow and evolve gracefully over time.
+
+  She'll also levy a challenge for the platform engineering community: The truly extensible platform of her dreams, one that's capable of solving the platform extension problem... Can we build it?
