How do I become genuinely interested in people?
Seems like quite a paradox to me. Furthermore you are posting this question on a pua forum which places a big questionmark behind the word genuinely for me.
But ontopic. There are three possible explanations for your disinterest.
1) They ARE boring.
But most of the people aren't if you look at them the right way, so this won't be the sole reason for your problem, but yes there are boring people on this planet.
2) You don't ask the right questions/lead the conversation. For example I love mathematics, but for most people that is like the most boring subject in the history of mankind, so I won't talk about it, or only tell the exciting parts (nerd mode

). I even scored chicks with talking about game theory.
I mean if a girl tells about her dog -I absolutely don't care a bit about dogs- I switch the subject to her, I tease her. Or just be honest and say I don't like dogs or whatever. If someone tells boring tales, why the heck should you be silent and listen to that. Just lead the conversation.
3) There is something wrong with you. You are depressed, autististic, or whatever. Seek a psych.
