The future of computing is certainly multimodal. What I see with beaming is being both hands-free and prep-free further enhances the spontaneity of life and helps fill in small gaps.
Printing otoh requires hands and prep. That's greater effort. You wouldn't print a recipe if you were just a little uncertain about step 3, you would ask for some kind of just in time modality instead. Voice might be fine for short info but sometimes you'd prefer to have it up and there's beam.
yeah, I don't disagree, though you could think that a robot with a heat-paper printer or pen could go a long way.
But more importantly I ultimately think that one of the unstated goals is to reduce screen time. And setups like these are only one voice command away from beaming youtube videos all around your house.
