Of course I'm not saying that overall our cities haven't increased in their background volume by virtue of more people and things such as air planes and leaf blowers, but to go another step further and call a entire generation of people inconsiderate and loud because they're used to being on a "solipsistic" internet smacks of a classic sense generational moral superiority.
And I'm also just as surprised that to come here, with as good of a community as I feel HN has, after scanning through the comments section, not a single person mentioned this in the first comment in each comment-tree. Instead it was a mess of "well, yes, us quiet people are so superior...".
