My experience is that people rarely feel constrained by bandwidth because everyone is fighting to optimize every last bit, often using varying techniques that sacrifice quality. Not a single video calling app that I’ve used recently feels like it’s actually delivering good video to me. They're all bitcrushed. They work for some meetings at work, but I would really love a much higher bandwidth connection for screen sharing on Discord and practically every streaming app.
Latency is also important: don’t get me wrong about that. But the fact that I have 1Gbps and I can’t get high bitrate video down kills me.
