Only time will tell who was wrong or right, simply put we don't know, i assume vaccine is a human invention, we have technology to manipulate our DNA and where i am positive that elite use this technology to find the genetic key for super weapon hidden on Earth , before actual aliens will do it.
Modern human DNA is a double Helix, so i even not sure how many DNA therapy we would able to take , before reaching the expected result.
Once again good question: why now to do such experiment?
First of all the scale of the experiment , the expected changes in the DNA , i dont think that we would see any remarkable results like in years , it's really long term plan.
The so called ascension isn't a self-improvement experiment , i highly doubt that you can reach such level with simple mantras and meditation, or exposing yourself to "cosmic" radiation or even go to the mountains and starving for some day, what i believe is technology.
I use proactive binaural for IQ improvement BrainWave generator software and some people go even beyond binaural's they use strobe lights , which can be even more effective (it's actually known since 70s and used by military for soldiers training and treatment).
Using strobe lights with binaural can potentially increase the frequency of the brain pretty much fast or it can guarantee good sleep, depends on program which you running with this device.
For example the newest Kasina Mind Media System (I have no affiliation with company, which sells this sound system), i have heard it is really good, but i didn't tried it yet, way to busy, but you can bet i will do it next year.
We can argue about, that spiritual enlightenment doesn't come trough technology , but i know what personally can effect my state of mind and i know how those effects to make permanent and for me its way easy and simple to use technology to reach certain improvements.
Sure you can do the same without technology, then do it , but i prefer my way of enlightenment.
