Yes, it is DISHONEST. And we know this because Asmamov, another "pulp" sci fi writer did this concept in the Gods themselves

Whole premise of this story is what a universe would have to look like in order for the impossible in our universe isotope Plutonium-186 to exist. And he's thorough and consistent about it. It is one thing go into speculative science, such as using FEV as a cover for supermutants and ghouls in the first Fallout (ie Genetic Engineering is the new Nuke), then to go to I love Nuclear Power trope which was known as totally false by the time of the first Fallout.
See, Fallout, the first fallout LOOKS like a pulpy B movie sendup, but it's beauty is that it's not. It's actually pretty smart, brilliant for a game that started out as a time-traveling dinosaur game. They did their homework....unlike almost every other Fallout game. Every outlandish trope of the first game was laboriously justified, and that's what made me a fan for life.
So no, you don't get to do whatever you want in an artistic piece. In this case, the ignorance of one generation becomes the outright lies of another. You wouldn't use pulp conventions to defend women being weaker misogyny or biological racism. And yes these are all in the same category because moral offensive and tastes are not the issue; the issue is factual correctness and the due diligence a creator owes his audience. If you want to reintroduce something like say, ray guns, you're gonna need a whole lot of actual science theoretical engineering to justify it as a desired effect even if it's not the most efficient.
Pulp rules don't excuse disregarding well known laws of nature. If you want effects like that, well, at the very least you've got to be more creative and do a lot more research than that.
EDIT: Avellone's a pissant, and he's ruined Fallout more than Emil and Todd ever will no matter how long they hold the license. Ulysses and the whole of Lonesome Road, also the letting go theme of Dead Money shows Avellone, who was thankfully not one whit involved in Fallout 1 has never understood Fallout. Fallout 3 didn't jump the shark, the Fallout Bible was the death knell of the franchise, and it continues to be a mortal wound into 76, even though it's not canon.
