  • Wayfinder can include different ticket types, including grilling, prototyping, research, and infrastructure tasks. 46:45
  • Matt has used maps with 50 to 100 tickets before reaching the destination. 46:45
  • He also uses Wayfinder outside code, including course planning and planning a garden office. 47:11
  • The broader claim is that engineering-like planning skills can transfer to other domains where people make decisions, gather information, and act. 47:11
