Bring back Sodium batteries and how to make them as well as solar panel production. Probably to Nikola Tesla.
To be a bit more precise whatever the easiest to produce versions of each are not the best ones so they could actually be produced at the tech level at the time.
I’m sure they would still end up creating equivalents of oil Barons etc. but at least it would be based on a cleaner tech and more able to improve from there.
Might have missed it but still shocked that there are only a couple models that go for more than one USB-C port.
I have been of the opinion that the adapters are acceptable because you gain flexibility with things like external DACs, which several people have brought up, but having to trade between charging and wired devices or a truly overkill dock style dongle just seems so silly when phones absolutely have the space to put two ports.
