Responsive design is making some web developers feel very smug and self-confident while raising the rates of User Experience and User Interface engineers everywhere because, Google.
Google co-founder and CEO, Larry Page, has said,
"We don’t necessarily want [our advertisers] to have mobile sites… I find I get frustrated on my phone when I hit these mobile sites… I just find it confusing… As an industry, we need to improve these experiences… I’d almost say that we shouldn’t be designing for mobile.

I’d like to see us move in that direction."
So, your Google search ranking on smartphones is going to be impacted if your site does not respond to recommendations put out by the search behemoth. This is something that has been part of Google's recommendations for at least a year, but the impetus for conformity to responsive design has gained greater momentum in the last few months.

Some websites use separate URLs to serve desktop and smartphone users. A faulty redirect is when a desktop page redirects smartphone users to an irrelevant page on the smartphone-optimized website. A typical example is when all pages on the desktop site redirect smartphone users to the homepage of the smartphone-optimized site. For example, in the figure below, the redirects shown as red arrows are considered faulty:

So, responsive design is good because it doesn't piss off Google's co-founder when he is on the road. It doesn't wear out Googlebots, who are going to take over the world and need all the rest they can get before they become self-aware and start massacring the human race, and it makes things faster for everyone.
