Not a direct answer to your question, but I interviewed a while back with this company called Fathom Radiant that's developing an optical computing system for AI training. It's further off than the next few years, but their ultimate goal is to use that technology to establish a computing center that outcompetes other options for training very large models, then leverage that position to support AI safety by allocating resources to groups that meet certain safety standards. It's an interesting approach and seems like a cool technology.

To add to that, it's been found that rather than depending strongly on a few genes, a lot of characteristics (e.g. personality traits, mental health conditions, etc.) depend weakly on many genes, as many as several thousand. Any single gene on its own may account for only a fraction of a percent of the total variance, which would've been undetectable until large enough data sets became available in recent years.
