He's not some random person. He's the CEO and driving force behind a company that is investing billions in getting to FSD.
If he "thinks" it is achievable with that short timeframe, he must have a project plan with milestones being predictably achieved in accordance with that schedule.
If instead there's no such plan, or the progress is not in line with prior internal expectations, he doesn't "think" it is achievable, he wishes it, and it is unlikely to be achieved by that time.
He said very clearly what he thinks is achievable. Full self driving in dev vehicles. No argument there. The OP was extrapolating this to other levels. What exactly do you have an issue with?
