Yes, there is surely evidence that intelligence is heritable, but it's worth giving the research on this a close reading. Current approaches can only explain 10% of the variance in intelligence (https://www.nature.com/articles/nrg.2017.104), plus the effects from the environment. My main issue with the article though was the assumption that a "best" set of genes exists without futher discussion (in addition to obvious ethical concerns)

I was just responding to this: "intelligence is a good thing, but the question is about whether there is a set of genes that are “best” for producing it. At the moment it’s unclear which genes those are"

Basically just noting that we now know at least some of those genes.

Many more will be found. Some will have other deleterious effects, and we'll figure that out too. The cause-and-effect of genotype and phenotype will be slowly decoded. It's just a matter of time; there's nothing unsurmountable here at all.

If there are 200 mind trait affecting genes you are saying a 2^200 search is fine.

That's... Not how any of this works.
