Of course. But how do humans learn to grade those infrequently-seen coins reliably?
He wouldn't be going through all this nonsense if he'd put his money into BITCOIN, amirite? Don't use bankruptcy as a scam. Especially don't try...
Can you say, in very general terms if that makes you more comfortable, what makes you think this coin is fake? I don't see the denticle problems,...
I'm becoming less and less of a believer in the special status of "human judgement". I think we're within shooting distance of trainable AI...

Doug, I've been making teasing comments on the assumption that everyone reading this thread already knew the contributions you've made to the...
I saw several of the Sigma machines at the big weekend show here. I'm still deeply skeptical of them, and I wonder how long it'll be before...
