Your data is legitimate, but you've got to ask yourself, would Jeff specifically and Google more generally care so much about it if it were also true for their use-cases?
- pizlonator 6y agoI don’t consider appeals to authority when thinking about technical issues.
- jlebar 6y agoThis isn't an appeal to authority. It's a suggestion that we consider the possibility that they are not wasting their time on make-work. This is Bayesian logic (our prior is that the systems engineers at Google are not incompetent), not an appeal to anything.
- pizlonator 6y agoJust because someone isn’t incompetent doesn’t mean that we should assume they are right. Highly competent people are often wrong. Questioning things is good.
