Isn't that because most of the other advancements/fads were not as widely applicable?
With earlier things there was usually only particular kinds of sites or products where they would be useful. You'd still get some people trying to put them in places they made no sense, but most of the places they made no sense stayed untouched.
With AI, if well done, it would be useful nearly everywhere. It might not be well done enough yet for some of the places people are putting it so ends up being annoying, but that's a problem of them being premature, not a problem of them wanting to put AI somewhere it makes no sense.
There have been previous advancements that were useful nearly everywhere, such as the internet or the microcomputer, but they started out with limited availability and took many years to become widely available so they were more like several smaller advancements/fads in series rather than one big one like AI.
