It seems unrealistic. We'll always have soap (it removes bacteria, doesn't kill it), refridgeration, boiling water, alchohol, Ultraviolet sanitization, microwaves (yep, radiation in general) and most importantly: biological engineering and accelerated evolution. So, we're to blame for "anti-biotic resistant" bacteria. I'm sure we can also be to blame for evolving better "anti-biotics" if we tried. That seems very vague, anyway. Doesn't she mean anti-bacterial rather than generic anti-microbiotics? It seems she must only be talking about antibacterial medicine, because I'm strongly doubting the idea of bacteria that is so well-evolved, it can never be destroyed. The details "An organism that rejects every kind of antibiotic" seem pretty ambiguous to me. Besides that, this article seems to have the same speculative manicness of the classic paranoic super-epidemic news headline. "It lacks substance."
It seems reasonable to be skeptical. I'm aware there's extreme habitatual bacteria that can survive immense heat and radiation, but I'm quite sure we (humans) haven't driven them to evolve that way.
Does anyone know of better sources regarding this? I couldn't find any, which is the reason I was perplexed.
