What commenters say

• Some commenters appreciate the complexity of elevator algorithms and share personal experiences with elevator scheduling systems.
• Others mention games and simulations that involve elevator scheduling, highlighting the challenge and satisfaction of optimizing elevator performance.
• A few commenters argue that elevator algorithms should prioritize factors such as load and passenger experience, rather than just minimizing wait times.
• There is disagreement about the effectiveness of 'smart' elevator systems, with some commenting that they can be frustrating and inefficient.
• Some commenters note that elevator systems are often designed with cost and efficiency in mind, rather than passenger convenience.
• The discussion also touches on the history and regulations surrounding elevator design, including the role of buttons and door timing.
• A few commenters mention alternative approaches to elevator design, such as express elevators and sky lobbies, which can be more efficient and effective.
• The conversation also includes references to other games and simulations that involve building and managing systems, such as SimTower and Project Highrise.
