WHY 2 ≥ 4 ON M1 MACS

I have groused about my new M1 Mac mini only having two Thunderbolt ports only to find out in this Rocket Yard© Tech Talk that two can be even better than four. By the way, my own tests, while not particularly rigorous, indicate the author's assertions are absolutely correct.

If we knew what it was we were doing, it wouldn't be called research, would it?
