I'm not a fan of "cost discipline." It sounds more like stingy, conservative, short-sighted, and backward.
My problem isn't with Google spending tons of money on "far out" things, it's with those "far out" things not actually being far out.
If they were spending billions to develop teleportation, anti-aging (both internally and skin/beauty-wise), intelligence/fluidity increasing drugs, disease cures, etc, then I'd be all about it. Especially if they were making progress, as another problem is setting out to develop teleportation, making no progress after 5 years, then continuing anyway.
There are also nearer-term things to work on like wireless charging, batteries with increased capacity (and/or more efficient/passive energy usage), solar/wind/nuclear power to add variety to energy sources, lower cost Tesla Model S equivalents (rather than the brute force approach being used by Tesla with the Model 3), etc.
There also more relevant education in schools (actual knowledge and skills, rather than an indoctrination with "smile, show up on time, conform, and do what you're told"), streamlining/elimination of politics (government), elimination of middle-management and company politics, ending hunger, getting rid of prejudice and inequality, minimizing crime (especially violent crime), etc.
In the grand scheme of things, they are really doing nothing, going nowhere, and spending endless amounts of money doing it.
Also, there are the crap products they keep releasing. Something needs to be done to put an end to that crappiness.
