Sort of. Now your cortisol could spike because of all kinds of things, none of which you can SEE. That's usually called anxiety. Back thousands of generations ago, if you were high on a rock by your cave with a good view, you knew you were safe.
Carrying this forward, we humans will have to work on better systems, because it's about to get worse/weirder. Our brains aren't designed to be good at detecting lies visually -- we have mental processes for speech, but visually, what you saw was always real. Now with AI in the mix, it's gonna get... messy.
And you still have to worry about traffic/accidents, performing well, getting fired or laid off, getting berated by customers/clients/bosses, plus any number of additional anxiety-inducing events.
Most of us would probably still take that trade, though: at least sitting all day kills you slowly relative to a mountain lion.
