25 years old, only worked in non-open office (cubicles) when I was an intern in college. Since then have only worked in open space. I love the ability to just put on headphones and grind away most of the day, but my coworkers that I work with most often are still literally just a chair pivot away. We turn around, collaborate on how to solve a problem together, then turn back to our computers and execute.

I think it's important to work on noise reduction through office design and offering quiet isolated spaces to work for people that need that environment. But overall I'm a big fan.
