My points on 3 capitals in AP apart from abv mentioned ones:
-Difficulty for employees- remember they came from hyderabad and settled in amaravati for improving governance, now they shd again mve to vishakapanam.
-planning and amount already spent on amaravati development
-no concrete guidelines for farmers who gave their land for capital
S i agree that decentralisation happens but most feasible way is to continue with amaravati and promote development of other cities in planned manner rather than shifting with no concrete planning
My personal opinion, i belong to AP
