Dear John: Farming and technology in the near future.

Posted on March 29, 2017 by Andrew Thaler

I wrote this story a couple of years ago and have been trying to find a home for it ever since. As the issue of proprietary software’s relationship to agricultural technology is back in the news, I figure it’s time to stop shopping this short science fiction story around and put it in front of a real audience. For some real-world background reading, see:

DEAR JOHN.

It started with the tractor. Or, rather, it stopped with the tractor. John Willis climbed down from the cabin of his dead machine and removed the cowling. Everything looked fine. The diesel engine shined, its green accents still brilliant.

After years trading his skill with a wrench and a soldering iron for access to his neighbors’ equipment, he finally owned a tractor of his own. The latest model, too. Not ostentatious, but with just enough comforts to make up for the last ten years. The tractor was new, bought debt-free through the Farm Act and a decade of careful planning and backbreaking labor. Expensive, but built to last.

Except it didn’t last. For the third time in an hour, the engine seized, the wheels locked, the console went dead. Willis sighed. He had acres to till and he wasn’t in the mood to spend a day stripping the engine, hunting for some tiny defect. He could send it to the service yard, but he couldn’t afford to wait for an authorized repair. The quote alone would set him back a week.

He couldn’t afford another late planting. Not this year.

He started the tractor. It roared back to life, the engine purred but the console beeped and flashed with panic, a thousand different alarms. The manual, a massive, multi-gigabyte document, was sitting on his work computer, back in the barn. For whatever reason, he couldn’t get it to download to his field tablet. He put the tractor in gear and continued down the field.

Fifteen minutes later, the tractor was dead again.

Well, he thought to himself, at least there’s a rhythm to it. He limped down the rows in quarter-hour bursts.

Hacking the Tractor: what the future of farming means for open science

I took a gamble when I bought the tractor mower. It was old, but well-cared for and ran well, but it was wearing out. Still, I couldn’t get a quarter as much machine for twice the price. Two months later, the mower deck cracked, rusted out from ten years of hard use. A replacement deck would run into the thousands of dollars, there were no options for just the shell, a cheaper, but still pricey option, and there were no off-brand decks to be found. Those three facts alone should tell you that we’re dealing with a John Deere, here.

John Deere made headlines earlier this year when Wired ran an impressive (and rare) expose on farm tech: New High Tech Farm Equipment is a Nightmare for Farmer. Deere followed up with a rebuttal letter, declaring that farmers did, in fact, own their equipment, while simultaneously outlining all the ways in which they didn’t: John Deere: of course you “own” your tractor, but only if you agree to let us rip you off.

Here’s the short version: Tractors are complicated and increasingly controlled by onboard computers. These computers use proprietary software, and that software is protected by the Digital Millennium Copyright Act (DMCA). The software itself is encrypted to prevent copying or modding. Those encryption are also protected by the DMCA. Breaking that encryption is illegal, regardless of the state of the software. If you have to decrypt the software to remove it, you’re breaking the law.
