Where did I say smart people having children is the only way to create smart people or that intelligence is only affected by genes? Please read what I actually wrote, not what you think I wrote.
Smart people are the people that have the ability to solve the hard problems we face. We have a huge number of very hard problems in the world and not enough smart people to solve them all. We need more smart people.
> "The best way we know to create more smart people is to encourage smart people to have more children"
...which is also unsupported by current intelligence research and still relevant to my counterargument.
It doesn’t matter the means (environment or genetic) as both will contribute to smart parents raising smart children (provided they have children).

Don't be ridiculous. If dumb people have more kids than smart people, the next generation will be dumber. Intelligence wouldn't have evolved if this wasn't true.
The idea that smart people are only produced by other smart people is nonsense. Genes regress to the mean, so most smart people won't have mostly smart children. And intelligence is significantly affected by nurture, not just nature.
And beyond all that, smart people aren't the end-all, be-all of humanity. They make useful things, but are of course capable of great evil (or mental illness or any other issue that limits their contribution to society).
