Back in the 1800’s people linearly extrapolated farmland usage, and concluded we’d run out in the early 1900’s.

It was about as ridiculous as the degrowth movement is today. Improving efficiency and decreasing environmental impact is almost always a better bet than embracing artificial scarcity.

[whaaaaat]

Improving efficiency sometimes comes with other externalities. See, for instance, massive CAFOs where cows basically live on mountains of their own shit. Or gestation crates, where pigs cannot even turn around.

These things are more efficient, but many people consider them inhumane.

Efficiency is always a tradeoff, it's not always better. It needs to be considered, and done with intention, not with mindless drive towards efficiency for efficiency's sake.

I like to remind people that the Lord of the Rings is about a villain named Sauron, who was a wizard/angel/god whose domain was crafting. He was originally a beautiful person, who just wanted to build more and more. But he wasn't satisfied with the efficiency of the humans, elves, and dwarves. Convincing them was much slower than just telling them to do what he wanted. So he made some rings to control them. And he started breeding orcs who would do what he wanted without question.

Sauron became highly efficient, but he lost his beauty. I'm not anti-efficiency, but I am "think about the tradeoff you are making first. Understand what you are giving up."
