However SpaceX have had certification for human spaceflight from the necessary agencies, have a strong safety record – comparable to competitors – and seemingly have a development process that is producing better hardware than Boeing at this point (as seen in the Dragon vs Starliner debacle). That's all radically different in approach to OceanGate.
While Musk and SpaceX in general sound like they're pushing the "move fast and break things" mantra I think they're more nuanced than that. It's more: move fast while things don't matter, so we can gather data and experience for when things do matter. This isn't much of a defence of Musk mind you, more of the team at SpaceX and the wider aerospace community.
