Yes, yes you are uncool. You are probably a nerd who likes to talk about topics of interest, rather than people and social matters.
Nerds are much more interesting, really. They’ve spent enough time on things they are obsessed about to have something to discuss. It’s not all “kids, schooling, housing, weather”. My favourite thing is to meet a nerd with an obsession outside of my own, as there is so much to learn.
Those will automatically not be my friends. Anyone who cares about sports (especially televised) or celebrities can go sit somewhere else. Or religion. Helps immensely with filtering as it usually is one of the first things you find out.
Talking nerd stuff is nicer and as such I only have nerds as friends and I married one, but there is no shortage of them. So far I made friends at any age (I am in my 50s).
