Not that I'm saying the structure of modern web applications isn't needed and that we haven't advanced. Just that the overhead and knowledge required to set up a modern web application is crazy.
I am working on a larger .NET web application in my day job... and it requires things like.. Typescript + typings files, Webpack/Gulp/Grunt/etc. and therefore Node.js and NPM, NuGet, .NET Framework, onion architecture, front-end framework (Angular, or React, or..), Entity Framework, multiple databases, web services/web API, ASP.NET MVC.. I mean, it's just crazy if you step back and think about it.
Sometimes I long for the simpler "bad old days"? Oh well, back to my enterprise single page application framework-laden monster.
DISCLAIMER: I know we're better off today in many ways, and maybe I'm just getting older and the cognitive load is higher.
