I would agree with the main sibling comment here. Pithy remarks about Elon Musk, about anyone really, generally don't add anything to the discussion and are very tired topics, particularly when they aren't even humorous in any way.

You actually make a fairly decent point (FSD being forever "soon" is one example), however in most of the businesses that Elon Musk operates in, delays or outright failures are extremely common (Tesla made electric cars appealing. Basically was impossible. SpaceX developed rockets in a "few years". Basically unheard of since Apollo-era. And so on).

So I would probably lean on the side of "give the dude some slack"?
