I think on HN we could and should go further in the "no-limit" thoughts, even if as a simple exercise.
For example, I always wondered why would Google need to make money. In some weird views, we could think the maybe it already have enough money to be self-sustainable, in financial orbit. Maybe they could put all the money they have in some low risk investment and use the annuity to paid engineers and researchers. They sure could cut a lot of expenses on PR and office prettifying.
Then a Google that was not required to make money anymore would really become something. It could provide every human with free internet without relying on forced data mining. It could pay researcher to produce open whitepapers on topics of their own interests.
This would working be a little bit like Universities in the middle-age or renaissance: having some funds, hosting interesting people, being a center for innovation, etc.
I do not think this is pure utopy, or to say it otherwise: only a massive ship like Google could carry such an utopian experiment.
