Nilay: Instead of putting Lithium ion batteries in phones etc, why don't people put a tiny bit of Uranium in them? Like a tiny nuclear power plant in things.

Me: 😱

Nilay: What? It's a good idea. You don't appreciate.

Maybe he has secretly been reading the Foundation trilogy. I mean, imagine everyone walking around with ²³⁸Pu next to their ears. As if the electromagnetic radiation from your phone wasn't bad enough.

(Did you know that there was a dictum in science fiction, that stories ought to be postulated on scientific concepts extrapolated from existing data/science. The Universal Speed Limit was a particularly inconvenient scientific law to obey. How would heroes travel from star system to star system at warp speed within their lifetimes? Asimov, while imagining science and technology in his fiction that would later be discovered/created in reality, more or less stayed true to this dictum.)
