That is not the kind of productivity that is the problem. People are talking more on the lines of factory and industrial automation. Please note in countries like India, land fragmentation, and lack of machinery to do mass farming/industrializing food production is the core of the problem.
There are also a range of things that might have to be done. Including taxing agricultural returns, defragmenting land ownerships, and changing nonsensical laws like letting only the farmers progeny be farmers. Then of course letting import of equipment to industrialize food production etc etc.
But India being India, I expect these things to happen at the very last moment. Like when everything is about to melt.
Which is why India is banning things like self driving cars. https://www.bbc.com/news/technology-40716296
