$12,000 is more than the average yearly income for a person on this planet. The USA has only 300 million or so people in it. What are the chances you are born in a place where $12,000 is considered 'the least expensive parts of raising a child'?

Would you have made the same argument for mobile phones back when they costed $12,000? I'm assuming that many people will want to use this technology.

[Eisenstein]

A mobile phone can be mass produced based on one design. This is not the case with removing eggs and doing custom gene work on them, incubating them, and implanting them in a person. You are making an invalid comparison. There are no 'economies of scale' with individual procedures.

It doesn't seem like you're addressing the HGP example, which at the time, would have been an "individual procedure" as well.
