They made fewer mistakes than anyone else ever has when landing a reusable rocket from orbit that way. I'd be OK with driving a car made by someone with that track record.

I'll bite; why do you think SpaceX was a mistake? They've had some pretty impressive achievements, all while actually making profit. Unless you meant individual errors like this month's landing attempt.

> SpaceX is proof his ventures are not immune to error.

Errors probably means errors here. As in yeah, most recently trying to land a booster on a barge and missing.

Mistakes happen. The wrong number in a configuration somewhere and everyone's car suddenly has a vampire that sucks down the battery 50% faster, or causes a misreading of wheel speed for anti-lock braking, or etc.

I really don't think you can consider SpaceX's first actual real-world test of a technology to be an error.

Do you mean "SpaceX was a mistake"? To me it read "SpaceX has made mistakes" (which you'd expect working with nascent technology).
