2. Hyping up cheaper sequencing the way you are is nothing more than what Sydney Brenner referred to as "low-input, high-throughput, no-output biology" (video source: http://thesciencenetwork.org/programs/reading-the-human-geno...).

3. Here's a more useful Moore's law derivative that's seen in the life sciences: http://www.nature.com/nrd/journal/v11/n3/fig_tab/nrd3681_F1....
You bring up another good point about "Eroom's Law" in which pharma productivity is actually decreasing, and that article was actually one of the things that got us interested in trying to do something new. What we are trying to do is to help reverse that trend by doing something different than what large pharma companies are already working on - if we keep doing the same thing despite ever-decreasing productivity, then I don't see how we can expect the trend to change.
You can sequence as fast and as cheaply as you like, but the big-O on biological research is not our ability to generate DNA sequences.
