The cloud might not be perfect but the baseline is already very good and should only get better.
Do we have reason to believe that it will only get better? I think it's possible the complexity of the systems we are building and the traffic they encounter will outpace our ability to manage them. Not saying I think it's the most likely outcome, but I don't feel as confident as you.
Food for thought for sure. True, nothing can get better forever...
But do we believe in "economy of scale" for computer and Internet systems in this age? Google, Amazon, Facebook, etc. have already proven to me that they have enough human and financial capital to architect and run systems that show economies of scale.
It's a bit scary to think about what it will mean when this runs out, but for now I personally feel confident that things are getting much better, and will continue to do so.
