In fiction, yes. Fictional technology appears overnight, works the first time without requiring continuing human effort for debugging and maintenance, and can do all sorts of wondrous things. In real life, the picture is very different. Real life technology has a small fraction of the capabilities of its fictional counterpart, and is developed incrementally, decade by painfully slow decade. If intelligent machines ever actually come into existence, not only will there be plenty of time to issue patches, but patching will be precisely the process by which they are developed in the first place.

Most programmers are supervised. So, this claim is hard to parse. Machine intelligence has been under development for decades - and there have been plenty of patches so far. One way of thinking about the process is in terms of increasing the "level" of programming languages. Computers already write most machine code today. Eventually humans will be able to tell machines what they want in ordinary English - and then a "patch" will just be some new instructions.
