Musk has lot of bold goals, but how many has he achieved?
Whether it’s a colony on Mars or autonomous cars, he thinks big...

I've participated in many risky development projects. The boss can only echo 
the promises of his engineers who may underestimate the difficulty of one or 
more critical functions they have really only guessed at without hands-on 
experience of how to address them. They may depend on their technicians to 
make the actual breakthroughs, I've come up with several project-saving 
solutions myself, twice cutting challenging computing complexity in half or 
more with a simple hardware change.

The Avro Arrow is a textbook example of wishfully overpromising more than 
engineers could deliver. In addition to rumored instability at the misjudged 
high end of the primitive stability system's speed envelope, which aborted 
the test flight with a US J75 engine just short of Mach 2 at only 3/4 of 
full power,  the combustion theory for its Iroquois engine, as well as the 
British RB106 and US J67, may have contained an incorrect model for high 
temperature flame dynamics that had been extrapolated from lower performing 
engines but didn't properly describe chemical reaction thermodynamics under 
extreme conditions not yet understood, at least by engine designers. For 
example at high enough temperature the combustion reactions may go both 
forward, releasing energy, and backward absorbing it (endothermic).
