will we be able to eat alien life for sustenance, and vice versa?
Frankly, ET never looked that appetising... and vice versa, let's hope we're not something they'd consider putting in their mouths.
Sure, it's possible. It's also redundant...enough plagues are already stored at Ft. Detrick and other places around the world.
That's the kind of thing that worries me... deadly contaminant stored in military facilities. There have been combat fatigued veterans of the Iraq and Afgan wars going ballistic on military based with conventional weapons, so what is there to stop a similarly minded soldier from accessing those 'plague' materials and going on a similar, but more deadly rampage. And the question would be: is the soldier to blame, or the government for storing such deadly compounds where they could be used? For mine, it would be the government's fault, for stockpiling those weaponised nasties to begin with.... and thus it should all be incinerated, without question.
As for government not wanting to develop newer chemical/viral WMD's, believe me, if government could take something developed for medical reasons and weaponise it to kiill more effectively over larger areas than its present stockpile, as long as my arse points to the ground [while my feet are on it, that is] government is going to do it.
And for anyone who thinks I'm just being a conspiracy nut, blame Hollywood for that, what with all the movies covering such matters, but there are likely some precedents if one cared to look in the right places [and didn't get caught].
