Remote work didn't kill collaboration. Invisible teammates did.

After working with remote teams, I noticed something interesting.
The biggest productivity problem wasn't Slack.
It wasn't Zoom.
It wasn't async work.
It was uncertainty.
"Are they focused?"
"Can I interrupt them?"
"Should I send a message or wait?"
"Is anyone even around?"
When those questions pile up, people stop talking naturally.
Instead they:
schedule unnecessary meetings,
over-explain what they're doing,
or simply work in isolation.
In a physical office, these answers come for free.
You glance across the room.
You see who's deep in work.
You notice who's available.
You bump into teammates.
Small conversations happen naturally.
Remote work removed all of those signals.
That's the problem I wanted to solve, so I built RovaSpace.
Instead of another chat app, it's a virtual office where your team is actually present together. You can see teammates moving around, join conversations naturally, react with emojis, collaborate in real time, and even use AI agents to automate routine work—all without constantly asking, "Are you free?"
I'm still building and talking with remote teams every week.
I'm curious:
What's one thing you miss most about working in the same office that no remote tool has solved yet?
