I think we're on the same page. It's a matter of $$ for speed in the sequencing and analysis phases. However, the big problem that Isaac Asimov posed and is still relevant, is the understanding of the results. Having your entire genome sequence is achievable now, but understanding it isn't. As far as I know 23andMe and other services only look for a subset of well understood variants and that's it.
Nebula has a 23andMe-like service with 100x WGS and provides traits that are actually polygenic and not just SNPs, so have some hope of being causal and not random associations… but it's still practically useless for all kinds of obvious statistical bias reasons.
For instance it says I'm "99th percentile genetic predisposition" for melanoma - yes, thanks, I know I'm Scottish - and left-handedness, which I'm not.
