>But you can only do that now, in hindsight.

No you could always do that. The meaning you take from it is up to you but you could always separate humans and calculators.

>No, that is not right. Fool’s gold is a thing.

I know what fools gold is. I used it for contrast. Fools gold can be tested for.

>but that doesn’t mean you know how to do it.

It doesn't matter. If you claim it exists but you don't know how to do it and you can't point to anyone who can, it's the same as something you made up.

>It’s like tasting two similar beers or sodas. You may be able to identify them by taste and understand they’re difference but be unable to articulate exactly how you know which is which to the point someone else can use your verbal instructions to know the difference.

You are still making the same mistake. Two similar beers or sodas taste different. No one is asking you to come up with a theory for intelligence. All you have to say here is the equivalent of "It tastes different" and let me taste it for myself. But even that much, you can not do. So why on earth should I treat what you say as worth anything ?
