The creation of the system is deeply impressive, so are compilers but I don't raise a toast to it each time I build my code. Like generated art, people aren't going appreciate it on the same level.
Not to mention that the less easily-explainable a technical achievement is, the less investment it will attract simply because fewer people will grasp the ramifications. You can describe AI in two words ("machine human") while it would take a few more to describe compilers in an instantly understandable way.
I personally think AI will end up sitting in the top 3 of these - but that is an opinion. I do think it is obvious it is at least _somewhere_ in that list.
I’m not sure I can get behind the “foundations are necessarily more impressive than edifices” view..
