@SecurityWriter @WowSuchCyber We're still talking Starship specifically, right?
The full stack is a vehicle nearly double the loaded weight of a Saturn V, two stage (my mistake; I forgot the plan is to boost it with a Super Heavy), reusable, with I believe 31 engines relative to S-V's 5 at the second stage.
They do have some of the best engineers in the ecosystem (I believe), but they're also trying to tackle the problem in a radically different way, using a remarkable departure from what worked in the past. This approach is, perhaps, open to criticism... It's possible the end-result of the Starship experiment will be "Well, it turns out we shouldn't build 'em that way for a reason." But I think we may be doing the whole enterprise a disservice if they're failing at inventing chess and we sideline critique that they suck at checkers.
