It's the engineers' job to resist with good reasoning.

It's the visionary's job to convince them that we people only think the impossible things are impossible.

That's basically how I do my internal dialogue. I shoot down an idea of mine because it's too brittle, vague, and difficult. But I still want to build that something. So, I keep thinking and end up saying to myself, "Well, maybe I could do something that's like an ugly partial implementation, just leaving out the hardest things: it won't be what I want but I can write something that resembles it." And then I write the first prototype and end up having something here to play with. However, I still keep wanting more and maybe I get an insight that allows me, having first played with the first build, to make a better approach with a new set of tradeoffs but such that will get me closer to what I want. Gradually I approach what I want, possibly never quite reaching that point, but still getting closer and closer.

While I don't disagree with you, context matters greatly here. This is the same logic of every middle managing pawn or upper management narcissist who self-styles him or herself the "visionary" you describe. Someone like Musk has the technical aptitude and experience to accurately assess what is technologically possible or impossible and estimate how much it will cost and how long it will take. He has also surrounded himself with highly talented technical people who, from what I can tell, he listens to.

Unless someone has previously envisioned and brought to fruition some visionary product or service, we should remember that the most likely explanation for their insistence that the seemingly impossible is possible is some combination of their ignorance, incompetence, and narcissistic delusion.

Yep, this is the point I was trying to make way upthread. If "the engineers just couldn't do it" is treated as a physical reality due to the objective hardness of the problem, and Musk recalibrates his future time-estimates based on that, great! If "the engineers just couldn't do it" is treated as a failure of the engineers, and people are fired for failing to conform to Musk's rosy estimate, not great!

And the latter is what you'd presume by default of a manager. It might not be true of Musk in particular, but in absence of explicit evidence to the contrary, it's likely, which is why this kind of overeager optimism can be downright scary-sounding coming from a high-level corporate executive.

I have a feeling that, like you said, Musk listens to these people. Maybe he actually knows their potential better than they know it themselves; knows what they can pull off when driven, that they wouldn't think (or especially claim) themselves capable of otherwise. Maybe, in other words, he's like the protagonist of some military ensemble drama series. (Jack O'Neill in Stargate SG-1, say.)

And given how successful he is, maybe he is that guy! Someone's gotta be. But that guy is really rare. Most corporations, sadly, don't have that guy anywhere in them. And without that guy, you've just got unrealistic promises, followed by flops, followed by finger-pointing.
