I don't know what "all those things are possible" means aside from "all those things are possible as long as we zoom together while in the office". You can screen-share in the office - as long as you are both on zoom ( or equivalent ) at which point why is it better to be at the office?

It would be harder in the office - too many people talking over each other in separate meetings. I can't imagine. So we all end up fighting for few conference rooms, or we squeeze once again into each others cubicles, losing the advantage of multiple screens and trying not to talk to loud and disturbing everyone around us.

I've spend decades developing in offices with other engineers, collaboration is always difficult when what you are collaborating on is always tiny text on a small screen. Zoom is better.

The places I’ve worked had lots of elegant and obvious solutions to shoulder surfing. Mirroring to a big TV was something we did all the time.

I find Zoom in particular to be a crude place to get this type of work done. Why do I have to send a huge video stream that roasts my laptop just to share a few kilobytes of text? I can’t scroll around or select text to point something out.

If the streamer’s text is too small, I’m shit out of luck there too.

Visual Studio Code has great collaborative coding tools that I have found work really well in a local network setting sitting near coworkers. Zoom is a total cudgel in comparison for this task.
