Elon Musk and the BFR

[Rynn]

I wish Musk would fund molecular manufacturing development rather than his Mars fetish. If he wants to live in an extreme, lifeless desert, the Atacama is way easier than Mars.

To be fair that's very much not in keeping with Musk's business strategy. Pretty much every company he has started has followed the principle of taking a previously established technology/service and working to make it cheaper via whatever means possible. Whether that be electric cars made cheaper through super-mass produced batteries or rockets made cheaper by reusability. Molecular manufacturing is a very disparate field, not an distinct technology, with far more speculative/lab based prototypes than proven products.
