Some technological wonder working in a way the observer doesn't understand may be perceived as 'magic'.
I think the same holds true for AI.
For problem fields seeming easy for humans, but hard for machines, the solution must be AI.
If a solution is found, the solution suddenly consists of procedures, if's, else's, and that dispells the magic.
So, in a way, AI may never exist.
99,99% of all known possible successors will just hotfix problems as they arise and blame everything on the predecessor. So just write up the things you need and tend to forget in a way you can use...
Promising costs nothing, it's the delivering that kills you.
