How does top half's letter disappear?
You start with single-stranded DNA and use a DNA polymerase enzyme to create a complementary strand (ie. create double-stranded DNA) from free nucleotides.
As you say, this
may have an effect on the genomics field, or it may not. I guess accuracy is an issue. Fast isn't always good if the resulting sequences are inaccurate. It all depends on the application and the questions being asked.

Now, I read the first page of that Forbes article (only the first page, I didn’t have time to read all 6 pages), and I have to comment on a particular paragraph that, for the most part, is complete rubbish.

You think you've heard this before, don't you? Genomics has certainly been overhyped--and so far failed to deliver on its promises. Many intelligent people have relegated the idea to the dusty corner shared by hopes for cold fusion, world peace and World Series rings for the Chicago Cubs. When scientists first mapped the human genome a decade ago, they bragged it would lead to cures for Alzheimer's, heart disease, schizophrenia and more. It hasn't happened. Drug approvals have gone down. The search for the genetic roots of heart disease, diabetes and other common ills has yielded surprisingly little useful information for the average person. Even 23andMe, the high-profile consumer gene-testing company cofounded by Anne Wojcicki, the wife of Google's Sergey Brin, had to lay off people last year.
What a load of twaddle!
Let’s break it down a bit:
Forbes said:

Utter and complete rubbish. Genomics is a well-established field of research that provides numerous valuable insights into both basic biology (genetics, biochemistry, development, evolution) and medical research (genetics disorders, developmental disorders, natural variation that underpins disease susceptibility and differences in drug response, cancer). There are numerous dedicated journals for the field and genomic research frequently appears in the top generalist journals (
Science,
Nature etc.)

Well, clearly the author is not one of these “intelligent people” of which he speaks.
Forbes said:

They did not. No reasonable scientist who knows anything of this area would have made such predictions. These sorts of ridiculous claims were made by journalists like the author. It was the media who are responsible for over-hyping, not scientists performing such research.

More ill-informed commentary. Research into heart disease, diabetes and other common ills has steadily progressed over the last decade. We know more about these diseases now than we did in 2000 when the first draft human genome sequences were published. And if drug approvals are down, it’s because we demand so much from new drugs. The efficacy and specificity that we require of new drugs continues to increase. I collaborate with a scientist who is in the drug discovery field. I have learnt from him just how difficult it is to find/create compounds that fulfil these requirements.

Consumer services such as this has nothing to do with genomics. This is simple genetic testing, ie. determination of the presence or absence of several already-known alleles of known genes. This falls well short of anything that would be considered as genomics, ie. looking at whole genomes.
