Surely Louisa, you're not suggesting that Musk may miss his target date? I mean, aside from dozens of such misses at Tesla, and lots more in every one of his other over-hyped companies, Musk has a perfect record. Albeit of over-promising and consistently under-delivering. But who cares when gullible investors throw billions at him and excitable journalists hype everything he does? Musk may not get to Mars, but he'll definitely get a footnote when A History Of Hype is written.
