I don't think the likelyhood of "electricity and Internet, running water grocery stores" being pulled out from underneath you (either by long term failure or prohibitive cost changes) is anywhere near as high as it is for subscription-based AI tools (at least not in the US).
That was a factor with electricity early on as it was first put to use. The flip side of the infamous "does it make the beer taste better?" adage/nonsense is that, per the story, back then you had breweries build their own power plants, because electricity was just that useful. It took a while for the market to start feeling comfortable with reliability of electricity supply and price point.
