Development was better when you must be at least this skilled to build software.
I read a post yesterday where someone was so proud of their bad permissions system... Well someone was unaware of how linux permissions and groups work and what a group even is was (and how it might be represented in a directory to be managed).
As for "web scale" well, all of that autoscaling is just auto-spending. "Cattle not pets" would be a great metaphor but cattle are valuable, most people are leased on chicken farming and own nothing. (If that analogy is lost on you, do your home work and be appalled, but it is on point).
Remember kids, its called a container for a reason, its how we isolate your shitty application from bringing down the rest of the system or the hardware that you dont understand!
