Its is what you do with it that counts.
What do you mean by this? Lets take steam. What I would do with it is build railroads for increase production! Or literacy, I'd use it to build libraries for increased tech and culture (so would the AI) Or calvary, I'd use it to whoop the AI who only had knights. (just like the AI would)
Sounds a awful lot like a tech lead gives you an advantage over rival AI's. So no I still don't get what you mean. How would you use these techs special that make them a waste of time otherwise?
Any victory, you need to beat the AI to accomplish it. And most techs give you an advantage, if the AI doesn't also have that tech. Like if your able to produce swordsman even though the rival nation can't even though its got metal. Thats a tech advantage one can use offensively or defensively. But if you both have iron working & metal, its almost the same as not having the tech at all.
Having iron working but the AI not having iron working... moves you closer to the short or long term goal of area domination. But having the tech but the AI has it too gets you no closer to any goal, except further up the tech tree.
If I can outproduce the AI via steam in my game, then I can overwhelm its forces easier and gain tech for trade easier (more food means more scientists) But if the AI has the same production boost, whats the point?
When I had a tech lead in magnatism, the AI had a hard time mounting any successful attack accross sea. When the AI got magnatism too, I lost some of that advantage. (not all of it because thats where my nice UU is) Thats what I call a tech lead, which gives you an advantage.
