Yes it will help. whenever we read about it we will understand how conceited we were and how we did not pay adequate heed to development all around. We ignored sea travel, forgot that the defence of India from land sarts from passes In Afganistan, built fotress mentality, thought bulky elephants were good animals , where as agile cavalry was more beneficial.
