Wow! This reminds me of a comment I saw on HN, or maybe it was a blog post about either Google's Project Loon, or Google Glass. I can't seem to find a link or the actual author, but they essentially said:

"What I care about is that Google has become a machine that turns advertising dollars into fundamentally groundbreaking new projects like Google Glass, Project Loon, and self-driving cars. They’re not just trying to make money: they’re trying to use that money on far-fetched moon-shot projects with the chance to be genuinely revolutionary. I admire that."

Now they are investing in a new realm where they are "excited about tackling aging and illness." Google's ambition, and vision is inspiring! Hopefully we see some innovation in this sector from this investment.
