I've been thinking about this myself. I concluded that if a Matrix-like option was offered (not forced), where your body would be used as a power source but your mind would be in some distant, impossible fantasy world which you are able to make up yourself, many people would take that option instead of continuing to live their normal life.

I know that if I were offered something like that, a world where I could live out fantasies with no conditions, other than that I give up my body, I may very well take it.

The end of humanity as we know it, perhaps, indeed.
