gweedo, as you are talking about math:

If you say something like: "it is impossible to brute force a private key, it would take many many lifetimes"
And I give you a key, that can be bruteforced in 10 seconds, than - by definition - your statement was proven to be wrong.

Stop playing this, let me use your words and twist them you know what I mean. Just generating a key pair is not brute forcing.

You got it wrong. What I mean is, I could generate a key pair, share the public key with you, and you would be able to recover my private key in an instant with any "script kiddy key cracker" in a manner of seconds.

Alone the existence of such key proves that it does not neccessarily take a lifetime.

That is impossible, so stop lying. If that is true do it on my address https://blockchain.info/address/1GweedoZJYb5CNLfSaBgBBYS2y7BMVb2Wo

He's not saying he can get the privkey for any bitcoin address, it sounds like it can only get the privkeys for certain "weak" addresses and close approximations for others. Some private keys should be MUCH easier to find that others, so this could actually be legit. If it's useful is a different question.

Then he is talking about hacking brain wallets due to the random entropy being a word or something easy.
