Uhmmm ok.

“How tall is the Empire State Building?” “About 1.216*10^12 HIVs tall”

But what kind of salt? Fine salt? Kosher salt? Rock salt? A slab of salt?

A grain, it says so in the title. All grains of salt are relatively the same size, and they are SMALL!

No they're not, there is a huge difference in size depending on the "type" of salt.

What is granule size of salt?

1-6 mm

Do you think 6 mm is large? Get out of here!

It's not about being huge or not, it's about relative size.

Table salt had tiny, sub millimeter grains, while rock said has huge, in comparison, grains.

When you're taking about possibly hundreds of times more volume, that does make a huge difference.

You are being dense if you don’t think “a grain of salt” is used to describe something very small.

You are the sense one here.

First, your failed to see that it was clearly a joke, for fucks sake, I'm taking about kosher salt in that first reply to the post, but that doesn't change the fact that salt, regular salt that everyone has access to, comes in very different "sizes", and when taking about electronics miniaturization, one order of magnitude of a difference in size is a veeery significant difference, and when comparing a grain of table salt and a large grain of rock salt, we're taking about more than just one order of magnitude.

Great, once these reach consumers you'll never be sure you aren't being spied on.

You realise I also make money too, in this arrangement. Right!
