That doesn't remotely begin to describe my inbox, but then again I haven't been in high school for a long time now. Where is the tab for "bills"?
These all seem like things people have in their email regardless of age. Your point seems pretty flimsy.
It's a label you create with a filter that has all the email addresses of your providers, so everything skips your Inbox and gets sorted automatically.
Who said GMail has to be designed for engineers? The majority of people have no idea what a filter is and wouldn't be able to figure one out even if you told them where to find it.
As long as the features that I need are there, I don't care what fluff they add on top, so long as I can turn it off. And I can turn this off.
Maybe this means opportunities will arise for a newer cooler mail service.
