These new foundations in particular should work equally well for archimedean and non-archimedean geometry and hopefully will be the right language for bringing together the Fargues-Scholze geometrization of local Langlands at non-archimedean places with a new geometrization at the archimedean place.  He describes as &#8220;(very) speculative&#8221; the possibility of a geometrization of global Langlands (with Scholze more optimistic about this than he is).<\/p>\n<p>Tomorrow Scholze will take over, giving the next six lectures.  Perhaps this characterization is a bit over-the-top, but seeing lectures of this sort and of this ambition taking place at the IHES brings to mind the glory days of Grothendieck&#8217;s years lecturing at the IHES on new foundations for algebraic geometry.  I fear that keeping up on the details of this as it happens will  require the energy of someone much younger than I am&#8230;<\/p>\n<p><strong>Update<\/strong>: Scholze&#8217;s first lecture is <a href=\"https:\/\/www.youtube.com\/watch?v=_4G582SIo28\">here<\/a>.
