Such strongly opinionated statements should be taken with caution. In our profession context is key and this theory does not always apply in every context.

Imagine if the Netflix guys were told to stay boring and not invent new shiny things? Ofcourse not everyone is in that scale.

I do not want to use the latest shiny tech but I do not want it to be boring as well. We are confusing KISS and boring here. A company I used to work at was running a job server at 90% utilization all the time and it even worked as a jump box, this is simple and boring but its also plain stupid. Invest some time and make it proper.

Maybe when I am 50 years old I will want a boring setup, but until then no. I want to be engaged and active in what I do.
