-# Real-World Benefits
-
-## Before Reflection (Our Game Server example)
-- 1000+ lines of serialization code
-- Prone to bugs due to serialization mismatching
-- Adding new features can imply making tedious changes to boilerplate serialization code
-
-## After Reflection
-- **0 lines** of serialization code
-- **0 serialization bugs** (if it compiles, it works!)
-- New features can be added much faster
-

-# The Bigger Picture
-
-This pattern extends beyond games:
-
-- **REST APIs**: Automatic request/response serialization
-- **Configuration Files**: Type-safe config loading
-- **Message Queues**: Serialize/deserialize messages
-- **Databases**: Object-relational mapping
-- **RPC Systems**: Automatic protocol generation
-
-With C++26 reflection, C++ finally catches up to languages like Rust (serde), Go (encoding/json), and C# (System.Text.Json) in terms of ease of use, but with **better performance** thanks to simdjson's SIMD optimizations.

-# Runtime dispatching is poor with quick functions
-
-- Calling a fast function like `fast_needs_escaping` without inlining prevents useful optimizations.
-- Runtime dispatching implies a function call!
-
----
-
-# Current solution
-
-- No runtime dispatching (*sad face*).
-- All x64 processors support Pentium 4-level SIMD. Use that in a short function.
-- *Easy* if programmer builds for specific machine (`-march=native`), use fancier tricks.
