What technological innovation do you think farming could adopt, that it hasn't already...? They don't operate with simple machinery. They regularly use some of the most complicated systems that mankind can build, such as satellite systems, chemical analyses, etc.
Governance is needed, where progress does not occur naturally.
invent, not adopt. that's the difference between government and industry, government doesn't invent anything except problems to manage.
reality is, governments want smallholding farmers out of the business and to replace them with agribusinesses because it's a process of de-kulakizing their subjects. it has nothing to do with science or environment at all. I think maybe a war over this stuff will give us the reset we need.
Governments invent things, endlessly. The infrastructure you are communicating with me was invented by a government research department. The encryption we are using to ensure we're actually communicating with HN, is a government research project.
Similarly, the solar systems on most farms, was a government research project. The satellite recon to analyse the farm - provided by the government to all farmers, including the tiniest hobby farm, is 100% government researched, deployed, and maintained.
Governments do a lot more science than you are giving them credit for.
