Would is used when talking about the future or a probability. So in the case of my discussion, it denotes a futuristic probability,  what that means is that, you don't have super powers,  what IF you had , what WOULD you do. IF and WOULD would always find their place in a sentence like this. I actually made the error, even native speakers make errors in write-ups.

Wouldn't say that I'd learn all of them, but If I could I'd certainly try. Starting with dead and complicated ones. Wouldn't you like to read ancient scrolls with knowledge our ancestors compiled all by yourself?

I think I would learn all the languages there are :D

Oh . I made a little error.Thanks.
