I run multiple SASSes for clients for myself and clients on far more "boring" stacks than this. One of them still has significant bits of VB.Net!

This post seems like a sea of trendy buzzwords to me. Maybe he thinks it's not trendy because it's not docker/serverless, but to me that stack is mainly a load of fads. React/Redux/Webpack are "standard", damn, 4 years ago you could have replaced that with a plethora of alternatives, as you probably will be able to in 4 years time.
