It's not necessarily fair to say that this method works on "high-security locks." There are a number of high-security lock systems that are either very difficult to bump, or intrinsically impossible to bump, like Protecs.
The larger threat of 3D printing and precise computerized machining, however, is that key control becomes far more difficult. It no longer matters if only one company can make the key for your lock: anyone else with temporary access to your key can just print one. Outside of unusual things like EVVA MCS, I'm not sure how this can be prevented.
