Rule of thumb for modern EVs is to not care about the battery at all. They are expected to last longer than the car. I would doubt even faster charging significantly changes this, or if it does it’s worth the trade off to those who need it.
Which is why I commented — because there was a blind spot to their point.
I interpret “modern EV” as an EV in the 2010+ era (as opposed to the original EVs from the 1880s-1910s, which were not modern) which were made for streets / commuting (as opposed to golf carts / theme park cars, which have been around for many decades). And I don’t think I’m alone when using this framing.
