There will be fewer and fewer AC public chargers and none of them will get upgraded. They barely get repaired.
It depends on where. AC charging will always be common, especially if you include Tesla Destination stations which I often use on my Zeros as well as on my Energicas. Free AC charging is just about everywhere you look in Reno, Carson City, Gardnerville NV, even some free AC charging here in Auburn, CA. The big advantage of AC charging is every EV made can use it, in one way or another. Could need an adapter in many cases, but that is not a big deal. And it is also common at home and in some motels.
Also, free AC Charging at many city halls, such as in Sparks, NV or in VA City, NV.
Not much need to repair them, they are cheap enough to replace. Not a whole lot inside of them. They are just 240 VAC supplies. I would be just as happy with a 240 VAC 14-50R. In fact, I prefer such as can usually get a lot higher current direct from a 14-50R than a J-1772 which can be as low as a shared 3KW which means 1.5 KW each side.
I find the big problem to be unreliable CCS.
