Human emotions
Human emotions are quite primitive, they are not a function of the times that we are in. After all, evolution is an extremely slow process.
That is why the sayings and teachings of ancient philosophers still apply to us, no matter what the circumstances, no matter what technology we have around us, and no matter what era we are in.
People have been falling in love. No matter what medium. In-person, sending letters, chats, long distance, short distance, etc.
