Over the past year I've been invited to, and become involved with, several organisations that are not within commuting distance. Video conferencing allows this, but it's still not great. Better video conferencing makes it a better experience, and more conferencing apps gives more choice, and makes providers compete to get better.
We don't need more video conferencing apps, but the end of the pandemic is mostly irrelevant.
There's a mutant strain in South Africa that could potentially be vaccine resistant. Let's hope either it isn't or that turnaround time for a modified vaccine is pretty fast.
Because many people will remain WFH even after the vaccine rollout. Video conferencing will be essential to connect those that go into the office with those who don't, especially during mixed in person/remote meetings.
