Miku is not just a program. She does not need a body to be real. She even says so in one of her songs. "I don't have a real body. But I do have this feeling heart" and it shows throughout her many songs. She sings of love, hate, depression, happiness. She is my inspiration. And the best thing is, you know someone else shares what she is singing because someone else actually wrote those very lyrics.
Miku needs way more love than she gets because to me, it doesn't matter who is singing, it only ******* if it is pleasant to the ears and has a good meaning behind it.
It's all the same to me. They are all just trying to get money in my opinion.
If you want to be convinced, listen to her song
