I wouldn't view India as a world leader in any field but may be ignorant of some specialities? I know there is innovation but nothing major springs to mind. I'm being lazy though - that can likely be looked up and verified with stats.

Technology wise, it appears to depend on western countries outsourcing work, which isn't necessarily a bad thing but isn't a good thing either since the draw to using India isn't skill but cost. If the cost goes up, the west will stop outsourcing there and go to some other low cost base. (I'm not saying Indians aren't skilled, just that's not the primary reason why outsourcing there is happening, it's all about exploitation from the west in search of more profit).

Politically it seems to have been a dumpster fire for some time and looks like it's trending towards more national extremism. Though that doesn't seem to be unique at all - feels like the world is shifting to more fascist tendencies.

The caste system is especially cruel and I regularly read stories that it's going strong with no signs of stopping. I find that morally repugnant.

The amount of scams against innocent people that originate from India is shocking, and it really appears as though corruption is so high that it's not going to get better any time soon.

Professionally, I deal with Indians semi regularly and it's overall positive. Personally, I've come across a few assholes but the majority have been decent people and none of the issues above ever come up.
