That is kind of my opinion too, that nobody is heeding God's warning, and are just continuing in their own little world. It's kind of like today, isn't it? It looks like not too many are paying attention.
Probably very similar indeed!
However,the more I think about it the more that "sons of God" keeps standing out and the fact that Jesus specifically mentions marriage sounds almost provocative considering 1st:the sons of God specifically took "wives for themselves" not just daughters,women etc but "wives" and 2nd: the obsession these days with alien intelligences,supernatural themes and entities,paranormal,new age conciousness etc etc etc ad nauseum.It seems a lot of modern culture spends a lot of time attempting to contact supernatural beings.And that without acknowledging God at all,in fact in a lot of cases in outright hostility towards Jesus Christ and the Bible.
I can't help thinking it actually is more than just a little implicit.
