Of course they don't understand it, their field is technology. Agriculture requires years of specialisation and most people here if they do have a degree are computer scientists, doctors, biologists, etc. But it's rare to find someone who has genuine passion and knowledge of agriculture. It is far removed from the city lifestyle and it is incredibly hard to break into, both for land reasons and because it's a hard job.
Moreover, agricultural sciences is probably just not a very commonly pursued degree for people in the city (citation needed).
So that brings me to my main point: disrupting an industry is usually done by people who want money when all the other good ideas have been taken. There is nothing wrong with this, but the cost with this fast paced approach is that the oldest and most complex industries like agriculture are going to put you in your place if you haven't done the work to understand them.
