I was reading about the Soviet
Lunokhod programme. They put a robot rover on the moon in 1970. To make the Steel timeline as work as printed what if manned space flight experienced significant setbacks but unmanned was wildly successful?
The POD would probably be 12 April 1961. Yuri Gagarin does not survive reaching orbit. I'm not sure if Kennedy would still commit to go to the moon without that. Even if he did the Mercury and Gemini programs fail in this timeline. America develops their own robots to send to the moon. Robot and computer technology get a huge boost thanks to the space program. In the 1980s robot tanks see production. People start to think about fighting wars by proxy entirely with robots. Computers to run the war machines get advanced. In the 1990s technology has advanced enough that manned space flight is attempted again. This time it works and humans move into already constructed facilities on the moon. 2010 sees the birth of AI and the Robot Revolt.
Since biotechnology wasn't developed as much in this timeline the plagues could be naturally mutated like the Bird Flu. After the uprising the Zoneminds start a crash course to engineer deadly diseases. Or they might skip that step and try to go straight to nanoburn.
What do you think?
