BTW the Genentech guy (Art Levinson) is on Apple's board, and in fact left Google, not Apple, when Google-Apple-Schmidt thingies went awry in 2009.
In the biotech world, at least while I was in college, Art and people like Craig Venter were the go-to guys when it came to DNA biotechnology.
I obviously haven't read the articles and what not since I want to read the biography as spoiler-free as possible, I'm curious what expertise Steve drew on, and what role, if any, Art Levinson played.
Art was also, as mentioned, on the Google board, but stayed on at Apple after leaving the Google board. He was more trusted, perhaps?
(I know, something is funky with my grammar today)
