Wrong.
We can and do un-discover technologies.
It has been:
▸ 20 years since a commercial plane flew supersonic
▸ 30 years since America brought >1 nuclear reactor online in a year
▸ 50 years since astronauts have gone beyond Low Earth Orbit
Your opinion about this does not matter.
Progress moves in one direction. Technologies do not get un-discovered. This is the worst and most primitive version of this tech that will ever be implemented.

This is truly miraculous.
They're using highly-targeted ultrasound to open up the blood-brain barrier, administer drugs, and combat Alzheimers, other diseases, and even addictions.
It's basically brain surgery without opening your skull. Wild.

The chemical difference appears to be that this thing has sulfur where LK-99 did not.
