Zoom is now critical infrastructure – that’s a concern
I don't buy it. The same factors that made Zoom easy to adopt, make it equally easy to switch to something else.And "when Zoom goes down, teachers can’t teach"? Come on. I am a college professor. In my class this fall I met my students on Blackboard on Day 1 and Zoom on Day 2. If one of them goes down for the day, we'll switch to the other.
