My opinion is it's a bridge too far to go to fully autonomous cars.

Some people don't like change, but you need to embrace change if the alternative is disaster.

It is a mistake to hire huge numbers of people to get a complicated job done. Numbers will never compensate for talent in getting the right answer (two people who don't know something are no better than one), will tend to slow down progress, and will make the task incredibly expensive.

If you had to buy a new plane every time you flew somewhere, it would be incredibly expensive.

Even if there's a zombie apocalypse, you'll still be able to travel using the Tesla Supercharging system.

Work like hell. I mean you just have to put in 80 to 100 hour weeks every week. [This] improves the odds of success. If other people are putting in 40 hour work weeks and you’re putting in 100 hour work weeks, then even if you’re doing the same thing you know that you will achieve in 4 months what it takes them a year to achieve.

I do love email. Wherever possible I try to communicate asynchronously. I'm really good at email.
