A big change from then to now for remote collaboration is better connectivity in general, and technology such as Zoom and Teams. But how do you handle the time zone difference? That has always been the issue I've seen with any kind of real-time collaboration with contracrors or employees in India. If it's work that doesn't involve that, then what is the big difference now? Github? Slack?

If companies like airbnb allow you to work from anywhere in the world, it means timezone is not a problem. It definitely needs some investment though.

What is the difference between pre-2020 full-time in-office, vs 3 day or even fully remote? Nothing, in my opinion (CEOs don't agree though). If people are productive with 3 days in office, that could have been the norm before 2020.

All you need is someone actually making it happen.
