For me, the idea of being offline is just a way to:
1. Get away with distractions
2. make side projects enjoyable and avoid burnout because it doesn't feel like another job
3. make steady progress because of 2
Because the major problem for side projects or solo developers is not productivity, it's they either get distracted or burn out then abandon projects.
People who work in teams mostly have fewer of these issues because they are usually being accounted. Plus modern technologies did drastically improved how organizations exchange information, as opposed to pure productivity gain (just try to compare modern organizations with Office-like software and Internet connections, to paper-based government systems a century ago). So you probably need technologies to efficiently exchange information in teams, but not so much as an individual.
