I'm obviously biased, but I'm building aq.dev, a shared workspace for running coding agents with a team, so I watch a lot of people's sessions more than my own haha.
If I'm between meetings, then I'm really watching 1-2 max. There could be a few others running in the background, but those I'm not paying attention to that much.
If I'm coding and in the zone, then usually 4-5 workspaces with 1-3 agents per workspace.
