I see what you mean, but I wasn't referring to Space X accomplishments but its ambitions.

The "we can probably land rockets and reuse them" is what it delivered so far, the claimed ambitions (laughable or not) are about making humanity interplanetary.

The number of steps between "I wrote a quirky database" and "I built a Dyson sphere" are substantially more numerous than there are between "I got reusable rocketry working cost-effectively" and "I used those rockets to put people on Mars".

While I agree with you on the guesstimate, surely you can't exactly know the number of steps in question.

Ambitions are free. Capability is expensive. Achievements are valuable. Ambitions do not predict achievement.
