I was recently standing in a bookshop reading Masterminds of Programming where the creators of programming languages talk about their creations. There was one chapter about Objective-C where Tom Love (one of the creator of Objective-C, along with Brad Cox) was asked why C++ had gone so far, while Objective-C hadn't:
Why do you think that C++ was used more frequently than Objective-C?
Tom: It had the AT&T moniker behind it.
Just that?
Tom: I think so.
What do you think about Objective-C today?
Tom: It still exists. How about that?
