Intelligence has been shown to have multiple genes plus major environmental factors tied to it. Same with photographic memory. As far as price. Wouldn't that be neutralized by more people offering the service and it becomes cheaper as tech advances. I.e. dead7 competition capitalism arguments.
And people already choose children's features now just by mate selection. Or even use of sperm donors. This would just make the outcome more accurate.
Manipulate DNA if problems arise just change it back next time.
That last bit is just capitalism arguments.
good points.
A human with DNA signature for swift retaining/recalling/applying info (priceless abilities) has little to do with their environment, thus the various teaching methods to address various learning abilities/pace
There're multiple car dealerships, but depending on brand and features to add, the car price will vary. And price increases even more if unique skills/techniques are required. Same applies to plastic surgery/cloning pets/restaurants/teaching....more services don't always equate to decrease in price
The only way to recall/fix bad DNA jobs will be to track patients and ensure they never reproduce, then update DNA technique for future sessions. Which is possible with a detailed service agreements and patients being honest. We currently can't get politicians and activist to agree on trangenders revealing their previous sex, so imagine asking them to agree with tracking/preventing reproduction
