I agree that we don't know how far "AI" will go in terms of real machine intelligence** but, give or take very specific and targetted examples (such as those "AIs" helping analyse the shape of various molecules in the search for new pharmaceuticals, and those looking for, say, tumours in scans), I'm with SFF writer, Charles Stross, on them: AIs are another scammy bubble (as seen with too many blockchain "currencies"***) intended to do little more than make their creators**** rich.
** - As someone who thinks that our intelligence (and consciousness, for that matter) "emerged", I can't rule out the possibility that it (they) could emerge in other animals or sufficiently complex software/systems.
*** - On the one hand, each new digital currency can add to the amount of digital currency available; on the other, each digital currency has a (an eventual) limit, so it's more like a resource than a currency... which means that the most honest thing about them (whether fake or real, scammy or not) is the use of the term "mining" to describe how new digital "coins" are produced.
**** - Obviously, those using such currencies to hide their illegal activities can, and very often do, benefit financially.
