PSA: This paper is quite a difficult read for "normal" folks i.e. those without much knowledge of "Higher Mathematics". However the first few pages and the last few pages try to bring together the overall picture of the argument presented and can be understood by the layman. Hence i suggest browsing the paper and skipping all mathematical details if one does not understand them but focusing on the big picture.
