I suppose if you read literally anything other than absolutely fawning worship of Elon Musk as history's most titanic genius as a "tear down", I could see that.
But... it is absolutely true that his business model is incremental improvements + economies of scale. Tesla and SpaceX aren't in the business of inventing fundamentally new things. They're in the business of making improvements to already-invented things, and mass-producing them to try to bring costs down. This is only a troubling thing to read if you're deeply invested in his cult of personality.
"Absolutely fawning worship" is unnecessary hyperbole, there is a vast amount of middle ground between that and your position. But I suppose if you can't make a reasoned argument, you have to resort to that (and we're off to the ad hominem races!).
"Most titanic genius" is more telling hyperbole, reiterated from your first post apropos of nothing. I didn't say anything about him or his genius, but you continue to mock and, yes, tear down.
When you say "Tesla is just [this]. SpaceX is just [that]," that's a tear down. You're reducing and diminishing companies that have undoubtedly made real impact, but why? Forget about Elon the Magnificent for a second, I would guess that you have similar things to say about Google, Apple, and the rest.
So I ask again, what company is doing things worthy of your respect? You're very good at reducing big things to nothing, but can you prop anything up? Can you support something? Maybe you're afraid to, because you know I can reduce and diminish it. That's easy, anyone can do it. But there's nothing interesting about it, there's no value, all it does is reveal insecurity.
One can say "this is not a revolutionary thing" without simultaneously saying "this is utterly worthless". Avoiding the hero worship and the personality cult does not require throwing out any idea of useful things coming from SpaceX or Tesla.
Yes, the world's outlook is pretty bleak.
Maybe you don't like him, maybe you don't like how much attention and praise he gets. But to be so dismissive of what those companies have accomplished with him at the helm, to me is just unwarranted bitter negativity.
In your mind, what companies are doing staggering heart-breaking Copernican-revolution work? What bar must be reached to not be "just applying incremental improvement and economies of scale?" Pretty bleak outlook if pushing the bleeding edge of rocket technology forward is humdrum small potatoes.
