One, as many point out, insurance is about covering the extremes. Most people won't use as much money as the premium, but others...
For example, a relative of mine got a rare cancer, that is pretty treatable, but the medicine alone would have cost 10k a month, ignoring the frequent oncologist appointments. No amount of savings would have covered that. Even a single visit to an ER could more than wipe out a couple of years of premiums.
The other thing is the discounts are no joke. Now if you are truly uninsured, many of the providers will upon negotiation give you some severe "break", but you have to fight every time and your results are unpredictable. The insurance companies have lots of leverage, and the providers jack up prices to make the negotiated rates look good compared to their alleged list prices.

The thing is 'AI' is a broad net....
So while you do have for example, utility in code generation, that ranges in usefulness to nearly the whole thing to mild completion, depending on the nature of the task. There's not going to be a full "going back", but maybe we can hope that people who are flooding with shit software they don't understand will get over it.
Which highlights one of the major real problems. AI enables people that have shit ideas to make shit content with unprecedented volume. This applies to code, video, text, music. The people that use it to make quality content might be seeing less than 20% more productivity as they keep it on the rails, the people making shit are now able to spew out 1000% more stuff because they just don't care.
Which in turn drives unreasonable infrastructure demands. So if the former "goes back", so too does the infrastructure build out.
The misinformation angle though...
