> "Chris just wasn't the right fit for Tesla, and we've decided to make a change," Tesla said Tuesday, according to The Wall Street Journal.

I wonder what "wasn't the right fit" meant for Chris' scenario. Did he walk away or was he let go because of team or company dynamics? Or was he not the right fit for the job? It'll be interesting as it can provide insight in company culture of Tesla vs. Apple.

Guessing as well — Tesla hired him for rock-star-coder cred, then found they actually don't need tools-work.

My guess, which I have no evidence for, is that Tesla likes to move fast (autonomous vehicle by end of '17) and at Apple he had a lot more time to focus on projects like Swift for longer periods of time.

Questionable. I would describe Swift as 'move fast' too, judging by the fact there is breaking changes [1] every release.

That's not uncommon for new languages. Swift is definitely not in the "move fast" column, even taking that into consideration.

Less than 4 years to become the dominant language for iOS development, thats pretty fast.

When you have a company like Apple backing it - anything can become dominant (at least till now).

Rumor has it that the culture at Tesla is worse than at Apple - more pressure, more bullies to please etc etc.

Doubt they are interested in writing elegant code there.
