Who's "we"? I have yet to see a high quality technical argument for using a number of technologies that have come along the last 5-8 years or so in most cases.

Who's "we"? I have yet to see a high quality technical argument for using a number of technologies that have come along the last 5-8 years or so in most cases. Too often "scalability" and "modern stack" are used as an excuse to tinker with the new shiny far out of bounds of their proper use. I have a reputation as being the opposition any time adoption of something new comes up. It's rarely necessary.
