Stating the obvious is not an ad hominem attack. Anyone who (honestly) thinks that because "devices" have not been engineered based upon a scientific theory somehow falsifies that theory is truely clueless (maybe ignorant would be a better word) of science and the scientific method.

Stating the obvious is not an ad hominem attack. I didn't say the author was an "idiot". Anyone who honestly thinks that because "devices" have not been engineered based upon a scientific theory somehow ''falsifies'' that theory ''is'' truly clueless (maybe ignorant would have been a better word) of science and the scientific method. A correct scientific theory must explain previous observations and correctly predict those to come. No where is there a requirement that it lead to engineered "devices".
