New comment by num42 in "Demand Is Booming for New No Tech, Repairable Tractor"

num42 — Thu, 04 Jun 2026 13:23:09 +0000

After reading the title, it reminded me of a high-tech bolt. I thought people were making even bolts more complicated, gradually finding ways to monetize them by integrating ads or unnecessary technology. Even bolts are becoming harder to use. It’s surprising to see that tractors are becoming less tech heavy now, as people prefer more usable and easy-to-repair technology again. MAKE ANALOG GREAT AGAIN(MAGA)!

Off-topic, these days information just goes in circles from subreddits, X, YouTube, and Hacker News to countless secondary sources, and then back again to the same original sources.

I am not surprised! The birth of computer science was rooted in the desire to automate mathematical discovery and proof writing.
