"Do responsive things. I didn't spend most of my early career convincing clients to let us do a responsive website just for you to serve me up a boring layout that kicks down to your mobile layout as soon as you are less than 1200px."

Can anyone elaborate on this? I feel like I'm missing some context because a desktop layout that kicks down to a mobile layout at a breakpoint sounds like the essence of doing responsive things.

Obviously there are a ton of other aspects of responsiveness, but specifically calling out the layout change makes me think I misunderstood something.
