I wasn't done tech trading, nosireebob:
I was fortunate to be able to hit up almost everybody in order to avoid the dreaded WFYABTA excuse.
I may have totally misinterpreted what you've written, but I've picked this out in case one of us doesn't understand WFYABTA and I'm honestly not sure who.
Did you mean you had several people to trade with so you didn't have to worry about those who got WFYABTA? Or that you traded with several people to postpone reaching the limit with any of them?
As I understand it, WFYABTA depends on the total number of techs you've traded with
all other civs, not the number you've traded with that particular civ. The limit gets raised slightly with each tech era you enter, but it's possible to meet some of the more stingy leaders and have them already say WFYABTA. Somebody please correct me if this is wrong.
The way around it, of course, is to get another leader up to friendly and then they'll happily trade anything apart from space-race techs. With 2-3 friendly civs you can merrily tech-whore like it's going out of fashion and not worry about the rest of the world. As things stand and neither Mehmed or Huayna will sign a DP with you to push them up to friendly, I'd just sign one with Cyrus (which will make you safe from harm unless he declares on one of the others) and not worry about anyone else. HC may be the tech leader, but he lacks aluminium, iron and coal, all of which are essential for speedy spaceship production.
In general terms, the bulk of Mongolia looks good for converting to workshops and watermills. Old Sarai, Turfan, New Sarai, and Kerkouane can take care of the most production, with a bit of help from Carthage if necessary. And speaking of Carthage, it needs a factory, not Taoist missionaries - any reason for those? You've got no unhappiness problems and no shrine so they seem like a bit of a waste, as any prophet generated now would be better saved for a golden age.
Health is going to be a minor problem until refrigeration/genetics, but I wouldn't worry about a little unhealthiness in the meantime, and as far as clean power goes, you've got uranium so if you can pick up Fission along the way, nuclear plants will take care of your needs.
I'd re-route your fiber optics beeline through rocketry so that you can get Apollo built while you're researching fiber optics to help speed things along. At the current rate that'll hopefully just mean 5 extra turns (if Cyrus lacks computers when you get there, putting 1 turn into plastics will probably make him trade, and then it's another 4 to research rocketry).
And finally, repeat after me: "Hannibal is
not a spiritual leader" - at normal speed it really pays to change civics in pairs rather than singly in quick succession.
Now go build that tin can to the stars.
