Indian cyber security and AI/ML based progress on the same is a joke. I don't know whom is the government fooling. Almost all government websites in India can't be accessed from abroad without the use of VPN. This only proves that how outdated and non robust the security set up is.
To avoid or minimize the cybersecurity incidents the government of India has reduced the exposure of their websites. I mean, what are they telling that if they close their eyes then such incidents won't happen?
I think, you need to really dig into what kind of people Indian government is recruiting to handle security. You are trying to be a global power and this is what the best you have got to prevent cyber security incidents.
Forget about developing an app that even comes closer to Instagram. The quality standards will suck. The old IITs have the capability and the youngsters can do it only if there is a private setup.
And most importantly any private firm having such app which stores data of a billion people will be heavily scrutinized in India by the politicians for vested interests.
