Since light bounces off walls and is thus confined to individual rooms, there is less interference and higher bandwidth, and traffic is harder to intercept from outside.

Aren't radio waves and light waves the same thing? Either this is in the visible spectrum and thus annoying as hell. Or it's just marketing's way of selling the decreased indoor-range.

It's interesting and I'd definitely like to see how this develops. What I'm worried about is interference from monitors and sunlight

But, if light bounces in every obstacle, it will be confined to just a room or so... Then, I think is unreliable for the general public and will be only useful in specific situations... Which I can't think of a single one... Not getting interference with Military, Hospitals and Airplanes isn't already achieved by separating special frequencies for WiFi and Bluetooth? How that is achieved today?

And not only each individual room, but do physical objects block the light transmission? So just simply moving around a room will constantly interrupt the connection?

I feel like even in situations where you'd use it in one room, Ethernet would still just be better

Could this potentially be viable as interlinks between multi-planetary satellites? Or are there solutions for that better worth exploring?

Im not sure light is significantly better than rf in space, but I do think this was in starlinks plans for inter-satelite communication.
