Input your distribution for the number of research-ability-enhanced children conceived per year that later go on to be research scientists.

Approximately 135 million children are born per year. On average worldwide, 5 children per 1000 go on to be researchers. In certain countries like the United States, 20 per 1000 children become researchers.

The total number of children born per year that later go on to be researchers is roughly 7 million. Remember to take into account expansions in the research sectors of developing countries.

• Claim: Based on popular opposition to "designer babies" and emerging biotechnologies like human cloning of any type, it is unlikely that this practice will catch on, and it may in fact be outlawed worldwide, meaning that the number of children conceived using this technique through 2070 will be trivial.
  Implication: Estimates and error bars close to zero.

• Claim: As with other medical technologies that were once feared and are now routine, such as the dissection of cadavers (300 BC), vaccination (1771), and in vitro fertilization (1978), it is likely that the world will largely embrace embryo selection, though it may take a few decades.
  Implication: Adoption similar to other widely beneficial reproductive technologies — high but not universal.

• Claim: Not only will the technology be considered acceptable, but it will be considered so beneficial that adoption is likely to be fast and widespread, similar to the adoption of condoms.
  Implication: Many millions of families will use the technology to give their children better opportunities, and within a couple decades from the introduction of the technology, there will be many millions of researchers who were born using the technology.

• Claim: Attitudes toward genetic testing and selection in China make it likely that the technology will be widely adopted there. The United States and other Western countries will then adopt it just to keep up.
  Implication: Millions of selected researchers will eventually exist, but not as many as if Western countries had adopted the technology willingly.
