U know, so far all sorts of ppl continue to swear that spacex, Tesla/SC will fail.
Yet, space is the cheapest launch system going today. And with the new BFR coming in about 4-5 years( ok, those are musk years; I suspect 5-7), it will be less than $5m to launch 150 tonnes.
Tesla has the only cars that are less expensive than comparable ICE versions. As such, Tesla now owns the NA market for sedans that cost 60k-200k. MX is finally eating into 60-200K market as well, and it appears that M3 will destroy the 30k sedan market and above.
As to solar, SC has 1/3 of the solar market AND is now producing their own solar panels that are cheaper than anything on the market ( and that was before China is hit for dumping ). New powerwall are affordable due to price differences. And Tesla roof appears to be on track to replace concrete and slate roofing.
As such, not much chance of failures.
