Number 2 is totally accurate. I can't tell you the number of stupid questions I have fielded by our Junior devs, just because I'm in their site line.

I have the unique experience of having been both in offices and an open floor plan (most recently) for the same company. I can unequivocally state that I was more productive with an office. Junior devs had to measure the opportunity cost of coming to my office before asking me a Googleable question, I'm fairly certain one of them doesn't even use Google anymore.
