> We benefited from text protocols because we had plenty of headroom: memory was cheap enough, storage was cheap enough, network was cheap enough, power was cheap enough for our use cases. But that's not quite so true anymore when you have to scale to support many connected systems and handle lots of data. The honeymoon's almost over.

Sorry, but memory, storage and network are all orders of magnitude cheaper today than when most of these text protocols were originally developed.

We have significantly more capacity today than we did back then. Thats why we waste all that headroom on reinventing everything in javascript.
