USB-C has solved about half the power adapter problem and could solve most of the rest with some more adoption.
Why do we not have universal batteries? In fact, we could probably just use USB-C directly. We are good enough at making small things that we could just choose a standard size, lile a Gopro battery, power bank form factor, with a male C connector sticking out one side.
Would it be slightly wasteful to throw out the whole pack with all the electronics? Yeah kinda, but better than throwing out a whole device. Plus, it would guarantee any battery powered device can be run without a battery at all plugged into the wall.
Failing that, they can just design a new futureproof chemistry-independant smart battery from complete scratch.
