Ah, I get it. The yellow and red triangles aren't promotions, they're advantages and disadvantages. The robot has Penalty Attacking Cities, No Defensive Bonuses, Can Move After Attacking. Two red triangles and one yellow triangle.
The 4 triangles are not upgrades. All it has is a yellow symbol.
Further, in the combat screen (i.e. decisive victory) there are no combat modifiers other than 65% barb bonus (likely because of policy unlocks).

If you look at the tech tree that i posted, it makes 70 known techs, and it still continue to the right.
Some upgrades could be effective in certain situations and movement upgrade clearly wouldn't have any combat bonus.
I pick 70 techs just from the "complete" Tech Tree posted by Arioch. Even in BtS, there were a total of 92 techs-so only a difference of 22 between the minimum Civ5 tech tree & the biggest Civ4 tech tree. Given that most of the missing "techs" are things which probably didn't belong in the tech tree anyway (like Meditation, Mysticism, Monotheism, Priesthood & Polytheism), then this tech tree issue doesn't seem like the huge "oversimplification" that some are claiming it to be.

That is not necessary true, I cant see any reason why the traits we know couldn't be bound to leaders, sure they seem a bit like they are more suited to the civ than the leader but there is no word on how it is coded in the game. Bound to leader or bound to civ. I think it is bound to leader, so the possibility for additional leaders for a civ exist for future expansion packs and mods. However that is just speculations from my side but you are also speculating. I am not saying that you are wrong just that there has been no confirmation.
This is Tech Tree for Civ 5! (better quality)

Do we know if the arrows in the tech tree are AND or OR pre-reqs?
