I do, but that post is arguing a point (Elon Musk doesn't know the difference between encryption and cryptography) that's unsubstantiated, while a plausible alternative explanation (he does know the difference, and mis-spoke, because he, like all other human beings, sometimes makes errors in translating thoughts into words) was proposed in my parent post.
Your post completely sailed right past that alternative plausible explanation, and immediately went back to asserting the unsubstantiated claim without addressing the alternative hypothesis, in what appears to be a bout of motivated reasoning against a figure that is politically disliked.
You don't get to completely ignore the point I'm raising, assert your own, and then play the "why aren't you staying on topic" card when your post was the one that brought up an unsubstantiated and unrelated response to the initial claim - that's hypocritical at best, if not outright trolling.
the point is less the infallibility of human cognition and more Spider Man's Law (with great power comes great responsibility).
if you're one of the most powerful people on the planet and you make public statements and decisions that will impact many people, you should be held to a higher standard of emission.
Other than me not making this claim at all, of course it’s substantiated, given he literally mixed up these terms people purporting that kind of expertise typically don’t. That’s literal substantiation, but whatever, I wasn’t even making that claim.
If it seems like I’m skipping past your point it’s because you’re not really making one, or at least not the clever one you seem to think you are.
To answer your q in good faith - yes, I have mixed up words, even in professional settings. I will then typically issue a correction, because the degree of such a mixup can cast a shadow on my credibility and can damage my career and thus earning potential. You seem to be taking the position that elon’s credibility cannot be questioned, at least on the topic of technical expertise. I find that a little bit (actually a lot) silly and an infantile way of looking at this.
Likewise, if I was routinely claiming to be this like, super technical genius founder engineer elite space dude that could never admit fault and was an expert at basically all topics, I would expect to be placed under the same skeptical lens (if not much more, given I’m just a low level grunt) I would face in a scenario like this in my day to day work.
