Funny thing is that this trend is the exact opposite of what has been the case in the past decades: things stopped being called AI as soon as they became broadly useful!
In my view, that's because scientists and programmers alike took AI seriously. No one was willing to claim "AI" as it was a holy grail, considered as-yet unattainable. What has changed since then is not really our capability, but our willingness to dilute the term for marketing gain.
