Do you think there could be lot of sapiosexuals in our society

Mostly, if you mean "people whose way of thinking I like". To be fair, "sapiosexual" is not a great way to define interest, at it's core it's just another version of "I'd marry anyone with big butt", or big boobs or anything. Except that people tend to judge intelligence on thinkign similar to themselves, or conversely, believe their love-interest is the new Einstein even contrary to all evidence.
