Historical Perspective: At Least This Time Around We Don’t Have Incubators For Incubators

Quis incubet ipsos incubatores?

Nice try though (I'm sure Juvenal would be proud) but custodiet is just a plain-old future, and incubo incubare declined the same way is incubet. See http://nodictionaries.com/novifex?text=Quis+incubet+ipsos+in... for details.

What was stupid about it was the scale with which both things were launched. Pet food, for instance, is the sort of thing that could easily have started quite small and grown as needs be, rather than having millions of dollars dumped into it. Webvan wasn't just grocery delivery, it was grocery storage too. In big, huge, expensive (california real estate) warehouses (refrigerated, to boot, IIRC).
