How is it possible for you to have been arguing about EVs for so many years, and still not understand basic things like "fast chargers are not just a straightforward replacement for slow chargers"??
We use slow chargers when we're not in a hurry to charge, which is most of the time, because cars are parked, most of the time. I have a slow charger at my house. If I go to a hotel, I need the car to be charged by morning, so I just need a slow charger. If I visit a town for a day, I just need a slow charger where I park my car. The only time I need a fast charger is when I am doing a road trip and want to stp for food and a charge.
Your concerns about the capitalist system's ability to provide all the chargers that are needed are unwarranted: the charging network is going where it's needed, and governments are actively shaping where chargers are going in for public policy aims, both as purchasers (eg local authorities buying and deploying lamp post chargers) and as regulators (eg requiring all motorway service stations to have at least six rapid chargers, requiring them to take contactless payments, etc).
As for fear of obsolescence, that's exactly why I've always got my cars on a PCP deal, and focused on TCO for the period of ownership (3 or 4 years), so that I can take advantage of rapidly improving tech. And it's paid off: my EVs went from 90 to 180 to 230 to 330 miles of range from 2015 to 2018 to 2020 to 2024. A decade of positive experiences. If you ever come to London, ping me and I'll take you on a drive around and you can see why I think they're great for tens of millions of people around the world (but not yet for you).
