> Never seen a workspace in the last decade that didn't either have a laptop and external monitor or multiple monitors.

I've never seen anyone using "a laptop and an external monitor" who actually uses the laptop screen. (Where by "use" I mean "looks at it." They might have it on, but it's usually just idle at the desktop.)

Personally, I plug my laptop into a monitor and then put it, closed, onto a little stand for ventilation. (One of these things: https://www.apple.com/ca/shop/product/HP9X2ZM/A/twelve-south...).
