This would be a good time to implement regulations and taxes on all robots to diminish all margins gained from automation.
Are you on drugs? If there are no margins nobody would even bother building a robot that actually can help with farm work. You point is so delusional I really wonder how you can develop this kind of mindset and still end up in a technology/startup community like hacker news.
If you have a substantive point to make, make it thoughtfully; otherwise please don't comment until you do.
