What is at all strange about wanting to work near other people so you keep each other motivated to remain focused? It's not magic, and it's not a treatment for ADHD (nor a replacement for such). It's just a common sense response to living in an age where everyone works from home isolated. Some people just work better with company.

Wow, I sure better stop doing everything in my life that there isn't literature on.
