So is the main difference instead of using the R markdown package to compile a PDF or whatever you use a standalone tool? I'm not quite sure what cross-language means here I guess. Does Quarto also offer more beyond what R markdown does in functionality? A quick glance at your site didn't show anything but I didn't look too hard TBH.

The idea is that we've separated running computations into pluggable "engines" (whereas in R Markdown everything was hard-coded to use R/Knitr). In Quarto we can use Knitr, or Jupyter, or Observable JS (and can add additional engines in the future). R Markdown was a tool created exclusively for R users whereas Quarto is for users of any language that want to create reproducible documents with Pandoc/markdown.
