I'll take you up on the disagreement. In the next 40 years, I find it very unlikely that any form of AI will be developed. Furthermore, we do want technological improvement in machine learning fields because of the advantages that can be offered in fields like self-driving cars, assisting doctors in diagnosing and treating illnesses, and many other fields.

And, because of the >40 year timeline, it will most likely be the next generation that leads the discovery to AI/FAI. So, we can't target particular people (although we can focus on those who are likely to have children to go into AI, which is happening as a result of this site's existence). This means that raising the overall waterline is probably one of the best ways to go about doing this, because children who grow up in a more rational culture are more likely to be rational as well.
