I find it amusing how people continuously claim to "know" what is and isn't possible based on our infinitesimally short stint into the sciences.
When I see articles like this, and especially with a "[likely] always will be" clincher I like to imagine how the exact same tone could be (and often was) applied prior to previous breakthru advances. Such as traveling several times faster than a horse could run. (Breathing would be impossible at such speeds!) Such as heavier than air flight. (A bird can fly because its body is optimized for flight but no matter what heavier substance you add to the body of a man it only makes him heavier and thus less able to fly.) Such as supersonic flight. (The "sound barrier" isn't called that for nothing!) and etcetera.
Until we really are omniscient any claim which depends on "we didn't know then but now we know" just shows the laughable hubris of the claimant.
