'Googleramus' era has dawned
We know what an "ignoramus" is: someone ignorant, often with the implication of claiming knowledge they do not have.
This person has acquired a digital age cousin who, immersing himself in the great pools of knowledge and nonsense in the unfathomable world wide web, emerges still without any real expertise or critical competence, yet arrayed in a formidable semblance of knowledge and ready in his own mind to do intellectual combat with all-comers.
We need a name for this modern relative of the ignoramus. The "Googleramus" perhaps?
