I guess it is an old argument. How willing are we, as a society, to protect people from being taken advantage of by cons. Musk had been extremely resilient for a con man. Probably because he mainly goes after relatively poor people.

Musk's companies aren't the only ones making breakthroughs in their respective fields. The only difference between Musk companies and others is that Musk just didn't care about safety, so his companies cut corners to make people think they are ahead. Other companies who are more responsible aren't willing to cut those corners for ethical reasons.
