That is certainly the case. And that is my point.
Society today and the limits of what you are allowed to know of reality are being, as they always have been, hidden. Reality is a secret. That is why Babylon was intentionally destroyed. That is why they ask questions of which the answers are often obvious. There is a strategy in hiding reality from others … and serious catastrophic consequences.
In order to know if something is wise to do, one must first know truth. If he presumes a truth that isn’t actually accurate, he surmises wisdom that isn’t actually wise. The temptation is then to hide the truth, “just in case while we secretly surmise the truth and predict wisdom”. It is the act of presumption, lust, and hubris. It leads to insanity. But it also leads to grand power over others because “knowledge is power”, especially the knowledge of how to keep the truth hidden and unknowable by others.
Someone discovers a means to live forever. Everyone, not in the know, then worries of all of the possible consequences of such a state. It isn’t because “no one knows”, but because some have kept knowledge very obscure from others and in so doing, have themselves been deceived. But then again, a very, very few, did not attempt to obscure truth from others or obtain power through deception. And for those, the real truth is more clear and consequences more predictable and certain.
But who is whom? Who does one believe when such games are played on such a vast scale? Do you believe those who say that we must keep it all secret so as to maintain control of it all? Or do you accept the proposal to more openly, but constructively resolve the reality of it?
It boils down to “who do you trust”.
I personally find that immortality isn’t actually an issue at all, and is in fact, almost the whole point to living in the first place. If one isn’t attempting the continuance of life, he isn’t alive.
But the fear of other people not being in one’s own control is strong and not entirely unjustified. Facing reality, the real truth, requires very careful learning of it, else the wrong temptations overcome the partially ignorant, making them far worse than the wholly ignorant, making them the “Niphilim” (monkeys with high tech explosives).
Thus there is a need for “controlled debate”. But with whom and to what degree of control? Until one knows the real truth, one cannot know to what degree it must be hidden nor from whom?
The Freemasons have fallen to this issue (as well as all secretive orders). The Freemasons use specific markers to identify who can be trusted and to what degree with which information. And that is fine until what has been called “The Devil” arrives on the scene, who proceeds to subtly cause those with good markers to become untrustworthy and those with bad markers to become the more trustworthy. By that strategy, The Devil then controls who succeeds and who doesn’t by causing those using trust to suppress truth and the lives of those deemed untrustworthy. The truly trustworthy come under attack by those who seek to only befriend the trustworthy. If the Devil doesn’t like white males, white males are tricked into appearing untrustworthy. The Freemasons then find themselves short of members and dying out. The markers become the means of deception and control.
I have been a part of that game all of my life. And to a degree everyone has. And when I say, “there is a way to fix all of it”, why should anyone trust me? How is anyone to even assess what I say when their prior knowledge is no more than disguise and obfuscation in order to hide the truth and tempt mis-belief? The solution is not in “who to trust”, but rather “who to logically debate and in what limited environment”. And the trust isn’t in the person, but in one’s own ability to honestly discern truth amidst the vast dark clouds of obfuscation that have covered the Earth for thousands of years while debating the angels challenging ones ego.
Truth and thus wisdom as to what to do with new powers is hidden from those lacking the courage to of humility. Only the truly humble can predict critical consequences with any degree of certainty. And in a world of deceit, where do you find those people? Certainly not in mainstream media, popular science magazines, or university lectures. 
Reality is a secret, revealed only the most humble (and usually un-trusted with bad reputations). 
And btw, I used the Stopped Clock Paradox as a type of indicator for me in order to see who, if anyone, was actually qualified to be a real scientist. A real scientist doesn’t take anyone’s word for anything (Nullius in Verba). The SCP smacks in the face of today’s science. Today’s science cannot answer the paradox and it reveals that today’s science cannot be truth. Physics forums do not even allow the subject to be presented. It takes someone who is truly humble and honest in order to dismiss the mass of indoctrination and even realize that the paradox exists (or someone who is obstinately against the mainstream). To answer it takes even more, far beyond the cloud that has been used to mask reality from your eyes and mind.
