I&#x27;m pretty sure preimplantation diagnostics are in many cases done with next-gen sequencing these days.<p>Also even accepting the idea that GWAS studies for IQ yield real and useful results (a claim most people I know in the human genetics field find highly dubious) CRISPR isn&#x27;t a panacea.<p>I posted a more detailed description above, but in short CRISPR causes a massively disruptive amount of damage in a cell. It does it very accurately, but a double strand break is definitely a Big Deal for a cell. This means it only works when you&#x27;ve got lots of cells to play with, a near-impossible task with human embryology.<p>CRISPR is an unbelievably useful tool for research and a huge advance, but it&#x27;s not the Solution to Human Genetic Engineering. We&#x27;re still a long ways from that.
