I disagree.
As an Indian. I think what our government needs to do is stream line the food distribution network and get products directly to consumers. Just doing this alone can solve some thing like 50% of the problems. Secondly they can start by leasing out large parts of underutilized land to agriculture related companies so that they can produce grains/vegetables/fruits etc in mass. Thirdly, to increase automation they can start by implementing tax friendly policies for machinery import so that human effort in agriculture can be reduced by bringing in machinery. Fourthly, to lay down a long term policy for irrigation infrastructure.
The problems with Indian agriculture system currently is too much fragmentation, middle men, lack of a well managed structure and distribution network. Too many people manually doing jobs and no mass production.
And soylent is quite expensive. $70 for one person, for 21 days? That is 4200 rupees for one person for not even half a month. With a little extra money you can feed a family of 2-3 on a good vegetarian diet here.
Soylent is just fancy Bournvita/Horlics/Complan/Boost/etc.
