Yes and no. I'm not sure Google's research into glucose-sensing contact lenses is motivated by R&D in any sense a Wall Street analyst would recognize. Likewise with their research into life extension science. These are decade long bets that do not slot into any commercial structure at the company. Sure, if they cure death, it'll be huge, but there doesn't seem to be a lot of urgency, or ability, to commercialize that research. More important than ROI are these two factors (IMO):
+ The founders retain a lot of control via the company stock structure, are nerds, and seemingly want to recreate a Bell Labs style culture.
+ Doing crazy science keeps up their brand as a tech thought leader current, even though 95% of their revenue comes from a pretty simple set of products that about 20 years old. This helps them recruit the best and brightest.
Doing this kind of research also gives them a plausible potential growth story to sell to the Street. So it's not that commerce doesn't cross their mind, but it's not in the short-term sense that a lot of people think of it as. I'm not opposed to university research, I just think people underweight the corporate side's contributions.
