Do the clones have belly buttons? I'm sorry, I had to ask...

But seriously, hopefully cloning - if it ever becomes reliably successful, it will still be prohibitively expensive (for most of us at least). Besides, I think the good old fashioned way of making babies will always be more fun.

As for creating a clone to be like a "spare parts" human of sorts... hopefully we will find other ways to grow organs instead of having to grow a person to pluck organs from as the original person's organs fail. Unfortunately... this leads to the stem cell debate, which is also a prickly topic.

I would much rather see money that might be used for cloning to go towards something like cancer research or something.
