In the Innovation Adoption Curve, we are absolutely beyond the Early Adopters phase and possibly the Early Majority. The growth rates necessarily have to start trending down because there’s no one left to sell to.
I'm not sure if the classic adoption curve applies. Has there ever been a product that vendors were shoving down customer's throats as relentlessly as AI?
Remember when we didn't have enough electricity for electric cars?

We need enough high speed chargers in the right places. The average American drives 37 miles per day. That pencils out to less than 30 minutes of charging per week using current high speed standards (which will continue to drop). Your friend could take their car at 20% if they knew that they could charge quickly at their destination.
We don't need a fast charger for every car anymore than we need a gas pump for every car. When I got my EV, I thought I would need to hire an electrician to put in a fast charger. After a week of just running the 1.5 kw slow charger I realized that was fine. Even using just that charger I am able to get 43 miles of range on my 10 hour overnight charge in an SUV. If you told me I was never allowed to charge at home, I would still use an EV. Parking at the charger while I shop once a week is fine. Most people with EVs that I talk to have the same feeling. Charger anxiety ends up being a non issue except for outliers that drive a lot, or in bursty patterns.
We need to have enough high speed chargers in spots where people spend at least 30 minutes per week, and that will cover the huge majority of driving.
Put high speed chargers at malls, grocery store and workplaces and it doesn't matter if you have a charger at home, you can just charge when your car is parked away from home.
I'm not even sure it's that big of a buildout that's needed. Where I am, there are far more public chargers (level 2 or better) than gas pumps. If I want to charge my car while I'm out and about, its pretty hard to find a commercial district where I would have to be more than 2 blocks from a charger (and I live in rural Canada).
This feels like a political problem (and maybe consumer perception) a lot more than an intractable one.

And by "slowly," I mean: Somewhere in the realm of 2-5 miles per hour. It's not fast at all.
But that's compatible with many lifestyles, wherein: The car is probably just sitting there at home for 12 or more hours per day, anyway.
If the round-trip commute is 30 miles, and the car gains just 3 miles per hour while plugged in, and it gets plugged in for 12 hours per day, then: It gains 36 miles per day, and the daily-commute part of driving it is completely covered by a regular outlet.
(Which still doesn't address the conundrum that many apartment dwellers face, but it would've helped me at most of the apartments I've lived in: Ground floor, and parking right outside of my place. I'd have just used an extension cord and the landlord wouldn't have said a word, except maybe to have a chat about how I like the car.)

Until free/at cost car charging is provided at work when the sun shines you're just moving the place where combustion happens.
This may be a worth while trade in downtowns where the main form of car pollution is engine exhaust at an average of 20mph.

If you have a charger or as many chargers at your apartment for the number of electric cars you know you are going to be able to charge with certainty.
If you have some small number of chargers at work do you know that you are going to be able to charge? Are you going to go into work park at the charging spot for 30 minutes then play musical chairs with your coworkers instead of working or are you going to park for 9 hours then leave at approx the same time as others ensuring that exactly 5 cars get charged per week despite being able to theoretically charge 336 per week in 3O minute blocks.
Regarding trips to the grocery store. Did you spend 30 minutes in a parking lot of a grocery store or mall this week? I haven't this month and even so you can't be sure that one of a small number of spots are actually available.
Currently plug in vehicles are what 1.9% of cars on the road. A relatively small number of spots scattered here and there is enough for this to work better than expected but trying to scale this begins to get pretty stupid pretty fast.
What does this look like with 1 in 3 cars? At 2 in 3 cars? How does it look like when you try to put enough chargers in the place where people incidentally land for extended periods of time instead of just putting them in lots of homes and apartments?

I agree. It has to be more viable than sending GPUs to space.
Both are questionable. Tidal power is super neat in theory but we really struggle to make it viable in practice. GPUs in space are probably the lower risk option, but with even more questionable economics My preferred outlandish idea would be to put the data centers next to solar farms in the Sahara. I just don't know yet how we are going to make the batteries to power that through the night

Owning an EV doesn't necessitate spending a few grand to have a fast charger installed. They charge fine from a regular 110v US wall outlet -- they just do it slowly. And by "slowly," I mean: Somewhere in the realm of 2-5 miles per hour. It's not fast at all. But that's compatible with many lifestyles, wherein: The car is probably just sitting there at home for 12 or more hours per day, anyway. If the round-trip comm…

Have you seen the price of electricity? That's with only about 5% of cars being electric. We've consumed nearly all of the slack in transmission capacity. I'm expecting transmission costs to balloon.

I drive a new EV in the Boston metro, I do not need to drive most days. Charging without an in-home charger is a massive pain even with Superchargers within 20 minutes drive and a 300 mile range.
A trip to the super charger takes about 1.5 hours assuming its available when I arrive, I can only make the trip when the car needs charging or I am wasting time and energy. The exact time I will need to make this 1.5 hour trip work is variable. It depends on battery conditions, traffic conditions, and what I need to do. I cannot assume that the car will be charged when I need it to be - if I need to depart on Friday evening, or unexpectedly needed to get groceries during the week - I am obliged to spend the 1.5 hours at that moment.
To avoid these problems, I generally need to charge the car when it has ~30-40% and for battery protection I can only charge to 80%. Turning a car rated for 310 miles range into one with ~100-120 miles of usable range and a 1.5 hour weekly maintenance schedule. That range could be further reduced to 50-70 miles in winter conditions. The stalls at charging station charge by the minute, so you can't exactly wonder off.
With a reliable home charger, these problems mostly go away, even a slow 5kw charger should charge the car overnight - and a typical tesla installation delivers 11kw. A renter with no ability to plugin and charge overnight will have a tough time with an EV compared to a gas car.
