Actually memory usage is and was speed too. Now CPUs are even faster still than memory. Just like then, you cannot just load a many megabyte map of nodes and expect pathing to churn it in 120 fps. Even with good cache locality. As a matter of fact, most pathing is local or inaccurate. The few exceptions I can think of are grand strategies and certain FPS that simulate world living beyond player's reach (immersive sims).
