I've seen it referenced here and elsewhere that Gorbachev didn't trust Reagan would share missile shield technology because the US had not shared ag tech with the USSR. What kinds of ag tech was he hoping for?
Well, I don't know if he had a detailed list or anything, but the specific line he gave to Reagan is that they wouldn't give him cow milking technology, so why would they give him space lasers? Which implies things like industrialized agriculture, which made US crops astoundingly productive.
