With 370 gone. Rest of India will be able to invest in Kashmir (Indian Kashmir).
Edit:
I gathered more information. This is quite beneficial for Kashmiris. Like really beneficial. Some of their new rights
- RTI (Right to Information)
- State elections every 5 years
- Reservations for minorities
- Special oversight and power of President in case of emergency
Not to mention biggest benefit would be investment from everywhere that will flourish the people.
