 ## Vulkan SPIR-V today
 
 SPIR-V for Vulkan models inputs and outputs as module-scope variables in
-the Input and Output storage classes, respectively.
+the Input and Output address spaces, respectively.
 
 The `OpEntryPoint` instruction has a list of module-scope variables that must
 be a superset of all the input and output variables that are statically
