Less scheming, more typing: musings on the Waltonian legacy in argument technologies .

The rich and complex legacy of Walton’s theoretical work for argument technologies is discussed. This is framed more as a call to action than as a prophecy: by calling attention to certain areas of Walton’s work yet to be fully exploited for the development of argument technologies, I hope to prompt scholars to take interest in them; conversely, by casting some reasonable doubts on the prospects of other lines of research inspired by Walton, I try to redirect resources and efforts towards more productive ambitions. My musings on this topic lead me to articulate two versions of argument scheme theory, discuss current limitations and future improvements of dialogue type theory, and critically assess the state-of-the-art of argument mining, as well as the potential for other types of argument technologies.
