...Considering how Intel has screwed up with its 14nm processes this could be a very real possibility...
I wouldn't put blame on Intel for "screwing up" 14nm manufacturing. Personally, I'm truly amazed at humankind being able to do this kind of stuff. The scale and the tri-gate transistor technology is simply mind-blowing.
Watch this:
And that's a 22nm tri-gate explanation. As far as I know, 14nm is much harder - and even more amazing. Even if you get delayed by a year or two.
