The lessons of history would suggest that civilisations move in cycles. You can track that back quite far - the Babylonians, the Sumerians, followed by the Egyptians, the Romans, China. We're obviously in a very upward cycle right now and hopefully that remains the case. But it may not.

Some companies out there quote a start of production that is substantially in advance of when customers get their cars.

Trying to read our DNA is like trying to understand software code - with only 90% of the code riddled with errors. It's very difficult in that case to understand and predict what that software code is going to do.

I think it's important to reason from first principles rather than by analogy. The normal way we conduct our lives is we reason by analogy. [With analogy] we are doing this because it's like something else that was done, or it is like what other people are doing. [With first principles] you boil things down to the most fundamental truths…and then reason up from there.

I tend to approach things from a physics framework. And physics teaches you to reason from first principles rather than by analogy.

If you think back to the beginning of cell phones, laptops or really any new technology, it's always expensive.

It's OK to have your eggs in one basket as long as you control what happens to that basket.
