There are many more interesting proposed approaches though. Like creating a religious cult around avoiding nuclear waste, all kinds of hostile-looking architecture, and my favourite is the idea of stocking waste in containers so durable that any people advanced enough to break into it would have to be advanced enough to know how to behave around nuclear waste
This was my favourite author in high school. He wrote this stuff in the early 1900 but it's still so relatable for modern readers. I highly recommend "il fu Mattia Pascal" (the late Mattia Pascal) and a little less recommended "uno, nessuno, centomila" (One, no one, and one hundred thousands).
When AA batteries go flat you swap them and the controller is already running while the old batteries charge on your separate charger, which you can't do with pouch batteries.
Also, it's a game of relying on a company's good will to provide a compatible battery, or of some Chinese manufacturer to provide it. While AAs are standard.
There's nothing that can change my mind on the subject outside of "these batteries are standard and available everywhere forever" which you can already say for AA NiMH batteries.
You have probably never played on a computer without Bluetooth, then (or headphones without Bluetooth). Using headphones connected directly to the pc is a pain in the ass. Using the controller's jack is much better.
You can buy a pack of 4 NiMH batteries and use the other two when the first two recharge. The problem is not connecting a charge cable, but the fact that all rechargeable batteries eventually die, but NiMH batteries can be bought at the grocery store, and be replaced by anyone.
Batteries and lack of audio are my only gripes with the steam controller. I still think it's better than every other controller, but I wish it had those. At least though, valve said it will be easy to disassemble with a screwdriver, so we will have a way to replace the battery with an after market one when it dies.
I'm not aware of any controller that can charge NiMH batteries tho. I think the hardware for that would weight as much as the entire controller. Also NiMH batteries don't do well with continuous charging via dock, unlike lithium batteries.
We all know which one is next tho
