I am arguing here just because there are way too many people like you, spreading LIES around. Be factual or be quiet, thanks!
No. There won't be such a machine, never. No matter how fast your computer is there's a theoretical minimum amount of energy required to compute a private/public key and the corresponding address. No matter how efficient your computer is, you won't be able to get below that. Practically you won't even get close. That means we are able to calculate the AVERAGE amount of energy needed to brute force the priv key for a given address, and that energy is far more than the sun emits in it's entire life. If humanity is able to use the energy of multiple stars we are probably advanced enough to forget about currencies in general.
So forget about brute forcing once and for all. However the algorithm can be flawed, but that's something else. Flawed usually means that you can speed it up by less than 100 times You would usually still have more than a lifetime to convince everyone to switch to a new algorithm.
