Of the four coding examples you describe, I find none of them compelling either in their utility or as a case for firing a dev (with one important caveat [0]).

In each example, you were already very familiar with the problem at hand, and that probably took far longer than any additional time savings AI could offer.

0. Perhaps I consider your examples as worthless simply because you gloss over them so quickly, in which case that greatly increases the odds in most companies that you would be fired.
