Love does exist. A few examples would be: - Passion for a hobby/job - The love of a mother towards her children - Many others that id be glad to discuss if needed
Telling someone they can or can't fall in love in the cyber universe is useless and your statement you will never meet is false, I know several happy couples who met on the Internet and are married in fact of all the ones I know that have gotten married none of them have gotten a divorce. you can find love anywhere.
While I do agree that your body's basic driving force is to pass on your DNA, I don't believe that love doesn't exist.
