Well, I wrote about the what, how, and when, but I never really explained why I am considering building the Oracle.
There are five ways to pop borders right now. As I said last night, I'd build it simply to pop the borders in WTF? because with marble Oracle costs about 80 base hammers and pops the borders after 2 turns. Barracks costs 60 hammers but gives 1 cpt, and I don't need the barracks for about 20 or so turns IMO. The monument costs 30 hammers but does nothing but pop the borders. The other options are to build a monastery in DF, then a missionary and spread religion, which would take too long and leave me without a strategic resource, or to hope for a random religion spread.
Hoping to luck out isn't an acceptable strategic choice IMO, so that one can be disregarded straight away. The monastery wouldn't be completed for at least 15 turns, and then the missionary would take a further 8 turns, 2 turns to get to WTF? and then a further 10 turns to pop borders means the borders wouldn't pop for 30 turns. That's just too slow. So religion isn't something I can plan for.
So the Oracle is a reasonable build to pop the borders, but if someone else built it, how quickly could I build a barracks or a monument? Well, as I'm expecting to chop 3 forests anyway, it isn't difficult to chop them earlier to build the barracks, and I'm dumping hammers into a barracks anyway whilst growing (because I'm currently paying for units already so don't want to build any more). So the Oracle plan wouldn't negatively affect popping the borders.
What I haven't considered which other players would go for it. There are three IND leaders, Ceil with Louis, regicator with Bismark, and scozed with Stalin. The last two have already built wonders, so they are likely to focus on growth for a little bit. But they are still going to be interested in getting MC early for their cheap forges. Scozed also have a holy city, and if they were the team that built the Mids, then the Oracle would maybe give them a GP for their shrine. I'd much rather slow them down and use the Oracle GP for a shrine for my holy city (this is one of the reasons why I continually built Henge in previous games).
The free tech isn't strictly a free tech for me, as I need to tech masonry. Adjusting for base beakers, if I were to take Monarchy which is 483 adjusted or about 400 base, I'd only be getting 310 base beakers for free. MC is better, at about 510 base beakers. But still, that's a lot of research for me at this stage of the game. If the Mids player gets it, they are going to have an even bigger lead to try to snowball from. No where near enough to win the game with tech trading on, but they would have cheap forges, rep and a large beaker lead. It's in my interests to stop them from having that advantage.
So the "Why?" is a combination of all of these reasons. If I focussed just on my own needs, then it might not actually be worth it to build the Oracle, but when the effects on the other players are taken into account, it becomes more important to try to take the wonder.
To put his in the context of current metagame discussion...your own growth isn't always what needs to be measured, or maximised. Sometimes screwing over other players is more important.
