I'm glad that Google has enough money to take on risky projects. So much of what they do fails - they essentially only have advertising. But to be honest nothing in that article seemed that world-changing or interesting. Even the nanoparticles are mundane and not much more of an extension of the work that's been going on since the 90s on bio-chips for detection.

But nanoparticles for drug deliver is interesting but they've been doing something similar with bio-engineered antibodies since the early 2000s. (in fact, if you're rich enough you can get a tailored cancer treatment with antibodies specific to your own specific cancer - this has been around for awhile)

I've long hoped that self-aware AI would come out of Google, but perhaps not.

In comparison, Elon Musk seems like the true visionary.
