Well arguably he stated the whole thing since Chris wanted it to be one language to rule them all from assembly to javascript. It was that moment I knew Swift is wrong from birth.
Now 10 years later, Apple is stuck with hundreds of engineers trying to improve the language, rewrite some of the API in Swift. And Apps as well. All with very little user benefits. This actually reminds me of Apple without Steve Jobs era.
Imagine if Apple had simply said we are going to use Objective-C for another 10 years on a wait and see approach. I think the decline in Apple's quality is simply because when Apple has too many resources, different teams are all trying to get resources and put something out for credit in Resume Driven development.
