Remote work is much more viable today than years ago. It won't take over, but it'll be a larger fraction of the workforce than pre-Covid.
While Zoom's overall usage seems likely to drop as the pandemic ends, it seems reasonable to assume that a large fraction of the pandemic-only users are paying nothing or only a modest amount. Further, educational institutions, which are more likely to stop using Zoom once the Covid threat recedes, almost certainly aren't paying as much as commercial users. On the other hand, Zoom's platform offers long term benefits to geographically distributed corporations which are more likely to pay for upgraded service levels. Zoom also has opportunities to expand into tele-medicine.
Another point to consider is that, even with rapid urbanization underway in many areas, a huge fraction of the world's population lives in rural areas. Technology, including off-grid solar+battery systems, Starlink, cellular Internet service, remote work platforms, etc. can bring many of the benefits of urbanization to people who cannot, or would rather not, move. (And then there are those of us who happily moved out of cities and into small towns in rural areas.) Zoom is one of the enabling platforms/technologies that is already equalizing opportunities across geographic and political boundaries.
