Nomuse ,
 Run carrara and look  in the credits and you will really find out who Charles is.
He created the Carrara render engine, Global Illumination, Physics, Caustics, Sub Surface Scattering, NPR and much  much more. So he is  responsible for what has been in  Carrara and what will be added in future versions.
Next time do a bit of research regarding who these persons are.

It is your choice to attend or not  that is all.
