I have been through the forums looking for an answer to this and all I can find are nonanswers. Can the AI win with a tech victory? I am interested because there is an AI in my current game currently researching Technological Victory. They're 59 weeks away so I can still do something about it if I target their research planets, but I need to start that now IF they can win through tech victory.
I'd preferably like to hear from people who have lost via tech victory.
