The previous RBI governor is entering politics and joining the opposition, so his current opinions should be taken as political rather than purely academic.
I don't follow what he says but I very much doubt his current opinions are any different from before. I've been reading about India + service economy + how great service economies are + how India can skip the manufacturing phase of a developing economy and jump straight into service economy in mainstream media articles in both US and India since at least early 2000s.
To provide more context on this, Raghuram Rajan participated in a march across India led by the then leader of opposition. He has not in any official capacity joined the opposition.
