I think a giant context is not going to be the answer. It's just got too many problems. Better will probably be parsing the context into connected pieces, and at a different level assembling the "lemmas" into "theorums". (Yeah, those aren't quite the right words, but I'm not sure the right words exist, and that's the analogy from math proofs. Code library isn't the right concept as the "lemma" will often be quite specific to the current task.)

Well, a baseball bat *is* a deadly weapon, if used as a weapon.

OTOH, when arguing about whether it's a bomb the definitions of the terms are less clear. And when arguing about whether it's an explosion, high energy chemists/engineers will have a different definition than folks who don't deal with the details.

To me, it's an explosion. If some professional wants to say "No, it's a deflagration." I'm not going to say he's wrong, but I'm not wrong either. We're just speaking different dialects of English.

That's not clear. The problems are real, but some of them already have solutions, and perhaps the others will eventually have solutions also. Also all of the alternatives have their own problems.

The folks working on sodium based batteries have made tremendous progress recently, but there's no proof that analogous advances aren't possible for lithium. At any particular time, you weigh your options, and decide based on the choices available, but that doesn't tell you what the choices will be next week. For that matter, lab results often don't scale commercially. So take this article with a few grains of salt.

Actually lithium should make more powerful and lighter batteries. That's been known for nearly a century. The details come when it turns to practical design.

I forget the details, but I seem to recall that lithium should be half again as powerful per unit weight as sodium. (That might be an underestimate.) But this doesn't include things like flammability, growth of metallic extrusions, etc. Dealing with the details can easily be enough to change that balance.
