All true across the board. We can also add that LFP batteries are technically a fire hazard but are already so thermally stable that thermal runaway is not possible.
I would qualify that range anxiety is still a minor issue. We’ve already far exceeded the 80/20 rule in most cars. But SS batteries will blow it away.
Your cost summary is correct. The technology is expected to be in supercars and premium cars only. Either way, the energy density issue also opens up new markets and applications. A lot of places ban ebikes and scooters because of fires on appartment balconies or from a bike on a commuter train. This battery technology is important.

The technology is great. A bit of a holy grail of ev batteries. The key feature is energy density two to three times as good, so you can pack more range with less weight and volume.
There are a few competing chemistries and all have their merits, but they are all not fire hazards. The highest performance chemistry has an unfortunate toxic gas problem if the cells are breached exposing the materials to moisture, but the others are chemically inert. (Like garnet). Long lasting. Can leave charged at 100% for long periods, no fire hazzards, and dense enough to give cars either lighter weight, or 1000km ranges. 1k to 3k charge cycles leave 80-95% capacity so they are very long life too.
Only bad news is they are still is early testing and have been 5 years away from production for 10 years, and still are. They are not fiction. There are small production lines for testing and optimization. They are coming. When and how much is the question.
Also China has a very close tech of mostly solid state batteries with a small amount of gel that has most of the benefits already in mass production in some of their cars.
The tech is awesome. End range anxiety and fire hazzards with amazing longevity, performance. Sweet.

Conscript who? Two out of three think it’s a bad idea because there is only one guy left to do any work.

Let’s not erase our history. This is who we were not so long ago. It’s still who a significant percentage of us are. Our job is to not let them gain power and undo the progress made.
