I'm not suggesting they need to be extreme in the other direction, just somewhat conservative.
That Google money can't last forever and it seems like they should be stockpiling a large portion of it for the long term, not blowing every dollar -- living, effectively, paycheck to paycheck.
I wonder if the employees/interns there have a sense that it's all eventually going to come crumbling down. Because I get that sense every time I hear about how they operate, and I really hope it never happens because I think they're a good thing in the world.
