I did not say that your farming techniques needed to change. You can do whatever you want. I was speaking broadly about farming techniques and technologies, not what you do on your farm. You do realize you aren't the only human on the planet, right? My only point is that this issue isn't binary, and that how things are and were aren't necessarily how they will always be broadly. It may not always be the case that farming is broadly done how it is today, meaning compute may still be worth considering even if one owns physical land.
I think physical space will always be important, but that doesn't mean it will on it's own be the most important thing or important in the same way it is now or in the past. Computers have already changed farming in some ways. You're free to farm however you want on land you own. I never said that wasn't the case or that computation would change anything for you. Consider not telling people they literally said something they literally didn't and instead be more precise in your own language.
