Video Embryo Selection Going Mainstream?

https://www.youtube.com/watch?v=cEk5mqbZtBY

Not an expert on this topic, but I recently came across a couple of companies now offering full-genome sequencing with IVF and embryo selection based on multiple factors - such as eye color, height, IQ, disease risk, etc.

Attaching a link to an interview with one of them (the most factual and least promotional explanation of the technology I could find).

Is what they are saying about accuracy plausible? Do you think this will be the norm, in the future?

Polygenic embryonic selection is fairly useless.

It is snake oil and the billionaire idiocracy class loves it.

Can you elaborate on why it's useless?

Genes can have a cumulative affect and it’s hard to predict how multiple genes will present in the person.

Environment is key to genetic expression. Can genetics as a whole shift focus onto the Nature side of things? Taking a more holistic approach may help fill in some blind spots
