This is a worrying trend I've been noticing as well. The last couple of years especially I've noticed a very large increase in people just not caring about graceful downgrading as well as people just not even testing in other browsers. I've had many conversations with people that are huge fans of Angular and Backbone and similar frameworks and when I mention people without Javascript I just get the canned "but everyone has Javascript turned on anyway and if they don't, too bad" response. Interestingly enough every one of them were also people who developed and tested only against Chrome and never even bothered to acknowledge other browsers. I know someone who is a developer who actually likes IE and uses it as their main browser and for years they've dealt with breaking bugs on sites like Github and other popular tech sites because people just don't even test in other browsers any more.
The cynic in me wants to say that this mentality is pushed for by companies like Google because no Javascript means no spying. But honestly I think it really just comes down to laziness. So few people truly care about their craft.
