@joany I understand this. Today I was in a Zoom call - and I'm not using Zoom that much. After some minutes, my Macbook Pro M1 Pro (Apple Silicon) was getting hot.
I can't believe how this machine can process audio and video "at the speed of light" (not exactly, but it's really fast) and becomes hot just for a call with 4 parties.
We need to concentrate more on software efficiency.
