el límite de la pesadilla

Frase interminable que acorto por respeto a todos mis amigos traductores:

Melancólicamente hube de contestarle que mi Universidad y otras ..., a los
que dedicaba entonces mi actividad profesional, eran Instituciones modernas a las que se podía solicitar noticia sobre cualquier tecnología de vanguardia por enigmática que fuera, o aplicación informatizada y robotizada hasta el límite mismo de la pesadilla -

My attempt:

Melancholically I had to answer to him that my University et alt..., to which I dedicated then my professional activity, were modern Institutions to which the news on any technology of vanguard by enigmatic they were, or application computerized and robotized until the same limit of the nightmare could be solicited

Sadly, I had to answer that my university and other universities to which I dedicated my professional activity at that time were modern institutions where one could get information about any cutting-edge technology no matter how esoteric, or any computerized or roboticized application, no matter how horrific.
