Not sure about the conditions of employment with Google, but if he has archives of emails long after he's left the company, could a lawsuit be forthcoming?
we really love katacoda! we're a bit more oriented on trying to visually explain what's happening (not there yet) and we're trying to give you a very high level of interactivity
No? How are they a threat? They spent money on Facebook ads and we don't even know if they came from the Government? By that standard, you can also say UK is a threat with Cambridge Analytia.
And the point being made is that other resources are being optimized for instead - wrinse cleaning uses less effort and thus time. The resource of concern varies by area as well.
Technically a nonpotatable unpurified water tap could be used for the same purpose but in addition to the risk of "oops accidentally drank direct river water with pollution and/or hazardous natrual bacteria" the infrastructure for the fringe use would be less efficient than just purifying more water to be flushed down the drain as a cleaning process.
Plus in say southern California the freshwater purification is not the limit but the input water hence the dirty looks for bottling it there instead of say the Great Lakes area where it is actually abundant. Hong Kong I believe is one of the few places that uses salt water to flush their toliets despite large seaside cities being in no way rare.
It is like mass production technically wasting more materials - at that point it usually doesn't matter compared to the sheer efficiency gains.
Granted non-sustainable uses of source water is something to be accounted for.
