1. Slower Knowledge Transfer: Teaching and learning would be limited to direct demonstration and observation, hindering the rapid spread of ideas.
  2. Slower Technological Development: Without the ability to document and share precise instructions, innovation would rely heavily on trial and error and direct imitation.
  3. Simpler and Localised Societies: Large, complex societies might be harder to maintain without the ability to communicate detailed information across large groups.
  4. Challenging Conflict Resolution: Non-verbal cues can be ambiguous and misinterpreted, leading to more misunderstandings and conflicts.
  5. Different Thought Process: Human cognition might develop differently. Language shapes how we think and categorise the world. Without it, humans might develop different cognitive strategies, possibly relying more on visual-spatial reasoning.
  6. Limited Problem-Solving: Problem-solving methods might be more intuitive and less analytical. Without language, the ability to articulate and systematically analyse problems would be limited.
  7. Different Learning Methods: Education would be highly experiential and apprenticeship-based. Learning by doing and observation would be the primary modes of education.
  8. Art and Symbolism : Art, symbols, and visual representations would be the primary means of conveying complex ideas and information.
